Intermetallic Nickel Aluminides as alternating Automotive Body Materials

Tomorrow’s car will handle better, be lighter, more fuel efficient and cause less pollution. One key technical design strategy for improving vehicles efficiency is the light weighting. The enormous potential of intermetallics especially aluminides stem from their many attractive properties, such as high oxidation and corrosion resistance and relatively low densities, combined with their ability to retain strength and stiffness at elevated temperatures. This intermetallic compound is also very good against corrosion. In considerations of the above, the aim of the present work is to alternate automotive body material with intermetallic Nickel Aluminides through mechanical and thermal characteristics. The prime focus will be on to obtain the mechanical properties such as tensile, toughness and hardness which were tested using Universal Testing Machine (UTM), Impact tester, and Hardness Tester respectively. Microstructural properties of these alloys were examined by X-Ray diffraction (XRD) and Scanning Electron Microscopy (SEM). Heat treatment (annealing) and Tafel extrapolation tests were carried out for thermal and corrosion properties of the nickel aluminium alloy
