Enhancing Microstructural Characteristics and Mechanical Properties in Friction Stir Welding of Thick Magnesium Alloy Plates through Optimization

2024-01-501402/06/2024

This research explores friction stir welding (FSW) to examine the mechanical characteristics and microstructure of thick plates manufactured from the Mg-8Al-0.5Zn alloy. Applying the FSW procedure to warm-form an Mg-8Al-0.5Zn alloy for the differential case covering the gears in the car’s automotive technology. Weld quality was significantly improved after using response surface methodology (RSM) to examine various welding parameters and find the best configurations. Improved grain refinement and phase distribution in the weld zone were found in the microstructural study of 11.5 mm thick magnesium alloy plates using RSM-optimized parameters. By dynamic recrystallization, the grain size was reduced to 16 μm, which is fifteen times smaller than the original material, thanks to the good results of single-pass FSW welding. Welding results showing high-quality characteristics such as tensile strength (161.8 MPa), elongation (27.83%), and joint efficiency (98.96%) were achieved using the

INVESTIGATION OF GASKET SEALING BEHAVIOUR OF AN ALL-ALUMINIUM HIGH PERFORMANCE, NEW GENERATION PASSENGER CAR ENGINE UNDER EXTREME ENGINE OPERATING CONDITIONS

2024-26-003301/16/2024

The increasing demand for higher specific power, fuel economy, Operating Costs as well as meeting global emission norms have become the driving factors of today’s product development in the automotive market today. Substitution of high-density materials and more precise adjustment of material parameters help in significant weight decrease, but it is accompanied by undesirable cost increase and manufacturing complexity. This becomes a challenge for every automotive engineer to balance the above parameters to make a highly competitive design. This work is a part of the Design and Development of 2.2 L, 4 Cylinder TCIC Diesel Engine for a complete new monocoque vehicle platform, focused on automotive passenger car application. This paper explains the selection of a suitable cylinder head gasket technology for a lightweight engine that acts as a sealing interface between the cylinder block and cylinder head.

Defect based fatigue life predictions for Aluminum Castings using Simulations

2024-26-028901/16/2024

Aluminum casting parts generally have inherent internal defects such as porosity which lowers the fatigue strength of such castings. Accounting for such a fatigue strength reduction for Aluminum casted parts is the primary purpose of this paper. Authors have used Murakami et al [1] approach to calculate a ‘porosity correction factor’ for fatigue. The actual material S-N curve is modified using fatigue factors to account for the fatigue strength reduction due to presence of porosity. This approach was then validated on one of the fatigue failure cases on Aluminum casted housing. There was a close match between the test data and proposed approach for fatigue prediction. With this approach, engineers will be able to do fatigue predictions in presence of material defects like porosity with simple porosity correction factor, rather than using complex modeling of porosity in FEA or using detailed fracture mechanics methods. Engineers can also be able to provide acceptable levels of porosity

FE Modelling and Experimental evaluation for the surface integrity of thin walled aluminum alloy

2022-26-120205/26/2022

The present study discusses the effect of installation torque on the surface and subsurface deformations for thin-walled 7075 aluminum alloy. A FE model was constructed to predict the effect of torque-induced stresses on thin-walled geometry followed by experimentation. Detailed surface analysis was performed on 7075 aluminum in terms of superficial discontinuities, residual stresses, and grain deformations. The localized strain hardening resulting from increased dislocation density and its effect on surface microhardness was further studied using EBSD and micro indentation. The predicted surface level plastic strain of 25% was further validated with grain deformations measured using optical and scanning electron microscopy.

Novel study on Elastic recuperation of Titanium (grade 5) alloy during machining

2022-26-116705/26/2022

Machining is the process of removing material from a workpiece, in the form of chips, to obtain the final part in its desired shape and size. Various aerospace materials such as Aluminum, Steel, Titanium etc. can be mainly shaped through machining process. Titanium alloys also find larger adoption in areas like Bio-medical and Automotive mainly because of their inherent high specific strength and consistent corrosion resistance. Machining Ti-6Al-4V (grade 5) has been difficult due to a number of its characteristics like poor conductivity of heat, strong and undesirable chemical reactivity with cutting tool materials at operating/ cutting temperature, it’s work hardening characteristics and very low modulus of elasticity. Due to low modulus of elasticity, the elastic recovery or recuperation of thin-walled Titanium grade 5 parts that occur after machining is an important topic/issue to be addressed since it has greater effect on the work piece surface quality, cutting tool wear and the

High Strength Aluminum Bearing Alloy with Increased Fatigue Resistance

2022-01-041103/29/2022

Aluminum-tin alloy lined bimetals have traditionally been utilized in rod and main bearing applications in light duty gasoline engines due to their combination of strength with soft-phase properties, such as embeddability and conformability. The load carrying capability of aluminum-tin alloys can be further increased by applying a polymer overlay, but recent advances in engine design, to improve efficiency and reduce CO2 emissions, have resulted in maximum specific load requirements beyond the performance limits of current aluminum-tin products. In these instances, the standard option would be to specify a lead-free bronze-based bearing solution, which has increased strength, but necessitates greater weight and brings a significant cost disadvantage over aluminum products. To address these problems, MAHLE have developed a high strength aluminum lined bimetal for use with a polymer coating, which offers a significant advantage in load carrying capability over traditional aluminum-tin

Analysis of Gasoline Engine Piston for Carbon Fiber Material

2022-01-040603/29/2022

In the present study, an automotive gasoline engine piston was designed and its various structural and thermal properties were analyzed for three different materials, namely, Gray Cast Iron, Aluminum Alloy, and Epoxy Carbon Woven (230 GPa) Prepreg. The design was done on SolidWorks 2019 and the analysis was carried out on ANSYS v18.1. The lightweight of the Epoxy Carbon Woven (230 GPa) Prepreg piston as compared to the other two pistons suggests that the inertial forces are reduced for the carbon fiber material. It is also observed that the structural strength of the Epoxy Carbon Woven (230 GPa) Prepreg material piston is more than that of Gray Cast Iron, and Aluminum Alloy piston. The temperature variation for the Epoxy Carbon Woven (230 GPa) Prepreg piston is less than that of the Gray Cast Iron and Aluminum Alloy piston, thus giving it a better thermal conductivity. The heat flux for the Gray Cast Iron and Aluminum Alloy pistons is greater than that of Epoxy Carbon Woven (230 GPa

Influences of Martensite Morphology and Precipitation on Bendability in Press-Hardened Steels

2022-01-027203/29/2022

Performance evaluation of martensitic press-hardened steels by VDA 238-100 three-point bend testing has become commonplace. Significant influences on bending performance exist from both surface considerations related to both decarburization and substrate-coating interaction and base martensitic steel considerations such as structural heterogeneity, i.e., banding, prior austenite grain size, titanium nitride (TiN) dispersion, mobile hydrogen, and the extent of martensite tempering as result auto-tempering upon quenching or paint baking during vehicle manufacturing. Deconvolution of such effects is challenging in practice, but it is increasingly accepted that surface considerations play an outsized role in bending performance. For specified surface conditions, however, the base steel microstructure can greatly influence bending performance and associated crash ductility to meet safety and mass-efficiency targets. This study reports and elucidates the positive effect of prior austenite

Development of an electric vehicle battery module laser welding process using SYSWELD and validation by test data

2022-01-037603/29/2022

With lightweight design in modern electric vehicles to achieve high energy efficiency, high strength and thin materials are widely adopted. For battery modules, 5000 and 6000 aluminum are typically utilized as a structural material with a thickness range between 1 to 5 mm. Laser welding is one of the most optimum welding tools for joining such a thin material due to its unique advantages, e.g., high welding speed, high accuracy, high energy yet the smallest heat affect zone, etc. This paper aims to develop an FE modeling procedure using SYSWELD to simulate the laser welding process used in electric vehicle battery module manufacturing. A sequentially-coupled thermo-mechanical analysis procedure is developed based on the welding processes for 6063 T6 aluminum alloys and the dissimilar joint between 6063 T6 and 5083 aluminum alloys. Different heat source models for laser welding are studies and compared. The effectiveness of the developed modeling procedure is confirmed by a large number

New Material for Battery Enclosures of Electric Vehicles

2022-01-026703/29/2022

In recent years, aluminum alloys have become the dominant material for battery enclosures used in battery electric vehicles (“BEV”) due to their low density. Aluminum battery enclosures, or other platform parts, typically provide weight savings of ~40% compared to equivalent commercially-used steels. The best-suited materials for battery enclosures are 6000-series and 7000-series aluminum alloys. Despite its light weight and recyclability benefits, the aluminum alloys have a crucial disadvantage if the heat generated by the battery cells raises the temperature of battery enclosures above 600°F/315°C. At the exposure of more than 300 sec at 600°F/315°C or higher, the yield strength, especially for parts that are in direct contact with the battery cells drastically drops by more than 70%, and in the critical situation of fire (~2200°F/1205°C), the batteries enclosures fail within ~5 sec, creating a paramount safety concern for BEV passengers.

Local Thermomechanical Processing for Improving Formability of High Strength Aluminum Sheets

2022-01-027803/29/2022

Limited room temperature formability hinders the wide-spread use of high strength aluminum alloys in structural body-in-white parts. Stamping or extrusion at warm temperatures or from softer tempers are the current solutions. In this work, our approach is to start with age- and work-hardened sheets from 7xxx, 6xxx, and 5xxx family of alloys and improve their formability using local thermomechanical processing only in the regions demanding highest ductility in the forming processes. The processes used were friction stir processing (FSP) and roller bending-unbending. In both the methods sheets were locally deformed and heated simultaneously without any change in the final sheet geometry or chemistry. Initial results indicated significant deformation in the processed zones with minimal sheet distortion. FSP also resulted in dynamically recrystallized, fine grained (d <5 µm) microstructures in the processed regions with textures significantly different from the base material. This resulted

Improving Keyhole Stability During Laser Welding of AA5xxx Alloys

2022-01-028503/29/2022

Laser welding of the magnesium-bearing AA5xxx aluminum alloys is often beset by keyhole instability, especially in the lap through joint configuration. This phenomenon is characterized by periodic collapse of the keyhole leaving large voids in the weld zone. In addition, the top surface can exhibit undercut and roughness. In full penetration welds, keyhole instability can also produce a spikey root and severe top surface concavity. These discontinuities could prevent a weld from achieving engineering specification compliance, pose a craftsmanship concern, or reduce the strength and fatigue performance of the weld. In the case of a full penetration weld, the spikey root could compromise part fit-up and corrosion protection, or damage adjacent sheet metal, wiring, interior components, or trim. The objective of the present investigation was to evaluate the effect of travel speed on keyhole stability during laser welding of AA5xxx alloys without and with filler wire in lap through joint

Magnesium Sheet Component Development and Demonstration Project

2022-01-028603/29/2022

Most of the applications of magnesium in lightweighting of commercial cars and trucks are die castings rather than sheet metal, and automotive applications of magnesium sheet have typically been experimental or low-volume serial production. The overarching objective of project was to develop new low-cost magnesium alloys, and demonstrate warm-stamping of magnesium sheet inner and outer door panels from a 2013 MY Ford Fusion at a fully accounted integrated component cost increase over conventional steel stamped components of no more than $2.50/lb. saved. The project demonstrated the computational design of new Mg alloys from atomistic levels, cast new experimental alloy ingots and explored thermo-mechanical rolling processes to produce thin Mg sheet of desired texture. A new commercial Mg alloy sheet material was sourced and pretreated with protective coil coatings, and its properties fully characterized. The Mg sheet was warm-formed using novel lubricants into intermediate size

Silver surface treatment applicable to bolts for motorcycles

2022-32-004101/09/2022

In motorcycles, the exposed mechanical parts play important roles in the styling design. The bolts that fasten these parts a good appearance in addition to the fastening function. Since many parts of a motorcycle are designed so as to appeal the mechanical and metallic beauty, needs are higher for silver-color bolts. Motorcycle bolts are exposed to the external environment, so they are required to have also cosmetic durability. Though there is a surface treatment having a higher cosmetic durability such as the chromium plating, due to its metallic gloss like a mirror, chrome-plated bolts are applicable only to specific models and parts. In this study, we developed a surface treatment that enhance the appearance and cosmetic durability required of bolts for motorcycles. The layer of developed surface treatment is dip coating with thin film polyorganosiloxane material on zinc plating. Clarified a zone where both the appearance and the cosmetic durability are attainable through the
