Abstract
This project describes the study of the mechanical and thermal property of Ni3Al to be applied on automotive body. Ni3Al is an intermetallic compound which has a unique property with temperature. It is a material which is lighter and 5 times stronger than stainless steel as temperature approaches 800oC. However, this material is expensive and is not common in the industries. Through this study, hardness test as mechanical property, and corrosion test is done on non-heat treated Ni3Al, and annealed Ni3Al specimens. Annealing is done at temperature 300oC, 500oC, and 700oC; soaked for 1 hour, and let cool at furnace for 24 hours. The material composition before and after annealing, is then analyzed with X-ray Dispersive (XRD) and Energy Dispersive X-ray (EDX) analysis. The results showed that Ni3Al have highest Vickers hardness value of 554 HV when it is non-heat treated. Ni3Al’s hardness drops as it had undergoes annealing process. Results also showed highest polarization resistance when Ni3Al is annealed at temperature 300oC which is 4154.95 Ω cm2. It also exhibit passivation behavior. On the other hand, XRD confirmed the composition of Ni3Al. EDX also had confirmed the elements of the material used in this project and it shows no other element exist other than Ni and Al even after annealing process. At the end of this project, it is found that Ni3Al is a promising material to be applied on automotive body as its hardness and corrosion resistivity is higher than current automotive material. However, due to its cost, Ni3Al may only be applied on high end automotive body such as BMW, Mercedes, Audi, and so on.
