Design of As-Cast High Strength Al-Si-Cu-Ni-Sr Alloys Using the Taguchi Method

2017-01-500909/30/2017

In the present study, a design of experiment (DOE) technique, the Taguchi method, was used to develop as-cast high strength aluminum alloys with element additions of Si, Cu, Ni and Sr. The Taguchi method uses a special design of orthogonal arrays to study all the designed factors with a minimum of experiments at a relatively low cost. The element factors chosen for this study were Si, Cu, Ni and Sr content in the designed aluminum-based alloys. For each factor, three different levels of weight percentages were selected (Si: 6, 9, 12%, Cu: 3, 5, 7%, Ni: 0.5, 1, 1.5% and Sr: 0.01, 0.02, 0.03%). Tensile properties such as ultimate tensile strength, yield strength and elongation at failure were selected as three individual responses to evaluate the engineering performance of the designed alloys. The results of the factor response analysis were used to derive the optimal level combinations. The alloy with the optimal composition had an average UTS of 267.00 MPa, an elongation at failure of

Development of Compact Synchronizer Technology for Manual and Automated Transmissions

2014-01-171904/01/2014

Advancements in engine technology have increased overall torque rating of engine and demanded further improvement in transmissions to sustain higher input torque. Conventional brass synchronizers have proved inadequate for these torque and gear inertia. It becomes necessary to use advanced material science and enhanced technology to synchronizer capabilities. Multi-cone compact synchronizer with carbon composite friction material technology has been tested successfully for these more demanding applications. This paper will focus on some of the key challenges in modern synchronized transmission, and way forward to address those. Some of the key areas delivering highest impact are being discussed. A combination of various techniques has enabled a significant reduction in overall transmission length along with enhancement in shift effort, life and overall performance.

Improving the Relationship between Processing and Properties of Zinc Die Casting: Developments in Creep and Ageing Correlations

2011-01-108204/12/2011

Most creep studies are conducted to determine steady state creep rate and time to failure. However, the priority for the designer is to predict the amount of total creep, being the sum of primary and secondary creep elongations, for a given service life under given loads and temperatures, for example 0.5% elongation after 3000h. An assessment of total creep behavior of industrially important zinc alloys has been conducted, and correlation/prediction curves produced. Another important property, related to creep, is stability after ageing, both for unloaded and also loaded castings. Recently developed relationships between natural and artificial ageing, and the correlation of mechanical property changes for different periods of artificial ageing with natural ageing will be presented.

EZAC™ - A Novel High Strength, Creep Resistant, Hot Chamber Zinc Die Casting Alloy

2011-01-108404/12/2011

Progress in recent alloy development work has resulted in the commercialization of a high strength, creep resistant, hot chamber zinc based die casting alloy. The work was based upon earlier research conducted under the sponsorship of the Department of Energy Cast Materials Consortium (CMC). Refinement of alloy chemistry produced significant improvements in tensile strength, hardness and creep performance. Because the composition of this new alloy is near that of the Aluminum/Copper/Zinc ternary eutectic, the low melting temperature enables the alloy to be cast in a hot chamber die casting machine without excessive wear of shot end components typically experienced with other high-copper zinc die casting alloys contents such as ACuZinc 5.

Recent Developments in Impact, Flexural and Fatigue Data for Zinc Die Casting Anti-Theft Applications

2011-01-108804/12/2011

Alloy 3, Alloy 5, ACuZinc 5, and ZA-8 were tested at five temperatures between −40 C and room temperature to determine impact properties. Izod impact energy data was obtained in accordance with ASTM D256. Unlike ASTM E23, these samples were tested with a milled notch in order to compare with plastic samples. In addition, flexural data was obtained for design use. Fatigue stress-life (S-N) curves and fatigue limits of die cast zinc Alloy 2, Alloy 3, Alloy 5, ACuZinc 5, and ZA-8 were determined using the rotating bend test. Fatigue limits for Alloy 3, Alloy 5, and ACuZinc 5 appeared to be higher and the fatigue limit for ZA-8 appeared to be lower than the values reported in the literature. The improvement in properties for Alloy 3, Alloy 5 and ACuZinc 5 is related to the presence of the die cast skin.

A New High Fluidity Zinc Die Cast Alloy

2011-01-108604/12/2011

A new high fluidity zinc die cast alloy was developed at Teck Metals' Product Technology Centre. This hot chamber die cast alloy is based on the commonly used ZAMAK alloys but possesses up to 40% better fluidity. Industrial trials and evaluations have confirmed the excellent fluidity of the alloy as well as the easy use and adoption of the alloy. Tests have shown the alloy has comparable physical, mechanical and corrosion properties as Alloy 3 and 7. The alloy is best suited to be used for casting parts with section thickness less than 0.45 mm. It can also be used for casting parts that are difficult to fill or have high surface finish requirement.

FPS - Friction Pad System

2010-36-045510/06/2010

The synchronization system was created with the intention to make easy the gear engaging in automotive transmissions. The speed difference of the shafts is reduced during the gearshift operation by means of sliding friction of the synchronizer rings. The constant friction performance can be improved and the wear can be simultaneously reduced either by additives in the oil of the transmission or by careful selection of the friction material for the synchronizer rings. Nowadays, brass or steel meet the requirement of both friction surface and resistance on the driving lugs. The friction coefficient of the surface can be increased by scatter sintered coatings, molybdenum or carbon linings that are joined to the carrier material using complex manufacturing processes. A new concept transforms this continuous friction lining into many single friction elements that are guided by "pockets" in the synchronizer ring. These "friction lining pads" require less material than the conventional

Black passivation films without hexavalent chromium on top of electroplated layers of zinc and zinc alloys

2007-01-259311/28/2007

Typical layers with cathodic corrosion protection for steel are zinc and zinc alloys. These layers are usually chromated and, for special applications, an additional organic or inorganic topcoat is applied. The most attractive finish is either black or clear. For aesthetic reasons, black coatings must be used for parts to be mounted in close vicinity of other black parts. Trivalent clear chromatings with good corrosion protection are nowadays well established in the production lines, but trivalent black chromatings are not. Development efforts were made to identify and overcome the problems and/or to find suitable workarounds. This paper will introduce a complete line of new products for producing black parts with high cathodic corrosion protection. This is: black chromiting on top of acid zinc and on top of alkaline Zn, Zn/Fe and Zn/Ni.

Notched Bar Izod Impact Properties of Zinc Die Castings

2006-01-051304/03/2006

Notched bar Izod impact testing of zinc die cast Alloy 3, Alloy 5, ZA-8, and AcuZinc 5 was performed at five temperatures between -40 °C and room temperature in accordance with ASTM E23 for impact testing of metallic materials. A direct comparison between ASTM D256 for impact testing of plastics and ASTM E23 was performed using continuously cast zinc specimens of Alloy 5 and ZA-8 at -40 °C and room temperature. There are differences in sample sizes, impact velocity, and striker geometry between the two tests. Bulk zinc tested according to ASTM E23 resulted in higher impact energies at -40 °C and lower impact energies at room temperature then did the same alloys when tested according to ASTM D256.

Selective Galvanizing Using Kinetic Spraying

2003-01-123703/03/2003

General corrosion protection of sheet materials such as steel used in automobile construction has reached a high level of performance, due primarily to the incorporation of mill-applied treatments such as electrogalvanizing, galvannealing and other coil-coating processes developed over the last half century. While such treatments have greatly extended the corrosion resistance of steel and its various body constructs, attention is now focused on aspects of the manufacturing process wherein these intended protections are compromised by such features as weldments, joins, cut edges and extreme metal deformations such as hems. A novel metal deposition process, based on high-velocity impact fusion of solid metal particles, has been used to extend the corrosion resistance of base steel and pre-galvanized sheet, by selectively placing highly controlled depositions of zinc and other sacrificial materials in close proximity to critical manufacturing details. The technology of this process is

Bolt-Load Retention Behavior of a Die Cast Magnesium-Rare Earth Alloy

2001-01-042503/05/2001

The need for improved understanding of new magnesium alloys for the automotive industry continues to grow as the application for these lightweight alloys expands to more demanding environments, particularly in drivetrain components. Their use at elevated temperatures, such as in transmission cases, presents a challenge because magnesium alloys generally have lower creep resistance than aluminum alloys currently employed for such applications. In this study, a new die cast magnesium alloy, MEZ, containing rare earth (RE) elements and zinc as principal alloying constituents, was examined for its bolt-load retention (BLR) properties. Preloads varied from 14 to 28 kN and test temperatures ranged from 125 to 175°C. At all test temperatures and preloads, MEZ retained the greatest fraction of the initial imposed preload when compared to the magnesium alloys AZ91D, AE42, AM50, and the AM50+Ca series alloys. The BLR behavior of MEZ did not show significant sensitivity to temperature within the

Study of Mechanical Properties of Both Magnesium Alloys AZ91D and AM50A Cast by Thixomag® Process Influence of Microstructure

2001-01-042003/05/2001

The forming of alloys from the liquid state can be realized thanks to various casting technologies where the temperature of the metal is high enough to fill a given die correctly. A variety of casting defects often occur in the final part, such as gas porosity, shrinkage porosity and hot cracking. In the case of the magnesium foundry, all handling of molten metal requires serious safety precautions to avoid explosion and burning. Protective gas mixtures (SF6, SO2, CO2) are used to minimize the ignition risks but have a bad impact on the environment. The semi-solid forming operates using a lower temperature in the solidus-liquidus range and seems to be interesting, in particular, for the quality requests of the die caster and for safety and a clean environment. The purpose of this paper is to present the mechanical results of tensile tests carried out on magnesium standard samples, which are cast by Thixomag® process from the semi-solid state. Two magnesium alloys AZ91D and AM50A are

The electrocoat operating windows of five automotive sheet steel products (uncoated cold rolled, electrogalvanized, hot dip galvanized, electrogalvanneal, and hot dip galvanneal) were compared. The effect of variations in base steel chemistry and galvanneal coating structure on the operating window were also evaluated. While all variations exhibited an acceptable electrocoat operating window, there was a measurable difference between the five sheet steel products. There was no effect of the galvanneal coating structure or base steel chemistry on the operating window.

Performance of Zinc-Nickel Alloy Electrodeposits as Affected by Internal Stress

1999-01-002003/01/1999

Zinc-nickel electrodeposited alloys prepared from alkaline and acid baths have been recognized for the excellent corrosion protection that they provide. For this reason these alloy deposits are included in a number of automotive specifications and are being used in a wide range of applications. One issue with these deposits is that they have the ability to “micro-crack”. Investigations into this phenomenon have suggested that the internal stress of the deposit is an important factor in the formation, and subsequently, the prevention of these micro-cracks. This paper describes the specifications for zinc-nickel alloy deposit to illustrate the performance expectations for automotive applications. The properties and characteristics of the alkaline and acid processes and the performance of the deposits are described. Then the measurement of, and characteristics of the internal stress are investigated.

Doped ZnTe: a Developmental Photorefractive Material

TBMG-3202808/01/1998

Zinc telluride is a semiconductive material that has been found to become photorefractive when it is suitably doped with vanadium or with manganese and vanadium. The combination of photorefractivity and semiconductivity make this material attractive for use in a variety of applications, including optical power limiting (for shielding eyes or delicate sensors against intense illumination), holographic interferometry, providing reconfigurable optical interconnections for optical computing and optical communication, and correcting for optical distortions and combining laser powers via phase conjugation. In comparison with other important photorefractive materials based on III-V and II-VI binary compounds, ZnTe:V offers superior photorefractive performance at wavelengths from 0.6 to 1.3 μm.

Mechanical Study of Thixoforming Magnesium Parts

98008502/23/1998

Nowadays the use of magnesium automotive engineering has become an essential way for weight reduction. The change from conventional materials, such as zinc alloys, to lighter weight materials, such as magnesium alloys, is realizable at commercially competitive rates. This requires lightweight solutions, optimized design and advanced manufacturing processes. The goal of this study is to validate the thixocasting process for a part of a wiper system. This paper summarizes the first mechanical tests carried out on a wiper part in AZ91 magnesium alloy by thixocasting and traditional casting process. The semi-solid die casting process enables to improve the mechanical behavior. To explain these results, the effects of microstructure on thermal properties are investigated and microstructural examination is also performed using optical microscope and scanning electronic microscope (SEM).

Specifying Zinc Alloy Coatings for Improved Galvanic Corrosion Performance

97100402/24/1997

Zinc alloy coatings have been used commercially since the early 1980's. Its origin is credited to both the Japanese and Europeans, where improved corrosion protection was observed over steed components. The coatings gained acceptance among American automotive companies in response to two industry-wide directives. The first was the mandate to restrict the level of cadmium on vehicles, beginning with the 1995 model year. The other was the challenge to extend the service life of vehicles to ten years, or in effect, to develop the “ten-year” car. Alternative finishes were sought as potential replacements for cadmium. Although a single surface finish has not been identified to have all of the functional characteristics of cadmium, zinc alloy coatings have many of the desirable properties. Among them are corrosion resistance and lubricity. Also, an added benefit is the extended corrosion protection that qualifies the zinc alloy coatings for the ten-year vehicle.
