Abstract

The growing demand for more fuel efficient vehicles to reduce energy consumption and air pollution is a challenge for the automotive industry. The best way to increase fuel efficiency without sacrificing safety is to employ aluminum alloy in the body of cars due to its higher strengths to weight ratio than those of conventional steel. Aluminum Alloy 6061 T4 was selected as a material for this study. The re-solution heat treatment followed by artificial aging as well as natural aging was carried out at different conditions in terms of artificial aging temperature and times. Charpy impact testing and Brinell hardness testing were performed in order to study and analyze the energy absorption and the strength Aluminum alloy respectively. SEM and optical microscope were used to observe the microstructure characterization of heat treatment and artificial aging aluminum alloy. The particular strength of this study is in providing insight into the current use of aluminum alloy and its future potential in car manufacture.
