Enhancing Microstructural Characteristics and Mechanical Properties in Friction Stir Welding of Thick Magnesium Alloy Plates through Optimization2024-01-501402/06/2024
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 CONDITIONS2024-26-003301/16/2024
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 Simulations2024-26-028901/16/2024
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 alloy2022-26-120205/26/2022
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.

Analysis of Gasoline Engine Piston for Carbon Fiber Material2022-01-040603/29/2022
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

Development of an electric vehicle battery module laser welding process using SYSWELD and validation by test data2022-01-037603/29/2022
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 Vehicles2022-01-026703/29/2022
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 Sheets2022-01-027803/29/2022
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 Alloys2022-01-028503/29/2022
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

Silver surface treatment applicable to bolts for motorcycles2022-32-004101/09/2022
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

Enhancement in Tribological Properties of Squeeze Casted A356 Alloy with Post Processing Techniques through Heat Treatment and Heat Treated cum Shot Peening Approach2021-28-026510/01/2021
Primary objective of this research work is to study the effect of heat treatment and heat treated cum shot peening processes on the tribological properties of squeeze casted A356 Alloy. The proposed alloy has wide range of applications in automobile industries due to its appreciable mechanical and tribological properties. Squeeze casting is an efficient economic and promising processing route for fabricating aluminum alloy with improved properties and pore free structure. Further the properties can be improvised through post processing technique like heat treatment and heat treated cum shot peening approach and also residual stresses are removed as a result of heat treatment process. So, this research work aims to investigate the effect of post processing approach on the tribological properties of squeeze casted A356 alloy.

An experimental investigation on hot cracking and properties of TIG welded AA2014 alloy using continuous current and pulsed current2021-28-026210/01/2021
AA2014 Aluminum alloys are most widely used for automobile and aerospace structures where specific strength is important. Hot cracking is a major problem while welding these alloys. In the present investigation, the metallurgical studies, viz, hot cracking sensitivity, microstructure and the mechanical properties, viz, hardness and tensile strength of the 4 mm thickness AA2014 aluminum alloy were studied using two different methods. The first method involves TIG (Tungsten Inert Gas) welding with continuous current process and the second method involves TIG welding with pulsed current process. In the both the process commercial argon pure gas was used as a shielding gas. The results showed that hot cracking sensitivity was decreased when the specimen was welded using pulsed current process compared to continuous current process. Similarly, the specimen was welded with pulsed current process showed improved mechanical properties compared to continuous current process because of low heat
