Abstract
The objective of this research are to investigate the damage process due to the fatigue failure on heat treated aluminum alloy 7075 with the effect of corrosion. In these research, the aluminum alloy 7075 been used because of it was the highest attainable strength level of all forged alloy and have a good corrosion resistance. Moreover, the aluminum alloy 7075 being used widely in automotive and aircraft industry. Many research on this material behavior being discuss nowadays because of it is important in safety and reliable. Many damaged from this material are related to the corrosion effect.In this research, three condition of specimen being prepared. The specimens is non heated, heated (T6 and RRA) and the heated (T6 and RRA) with effect of corrosion. The sample been tested mechanically to investigate the damage process to the aluminum alloy 7075. Here, the result of each specimen of tensile testing, hardness properties and damaged due to the fatigue been discuss to investigate the damaged process. Then the failure sample been cut and polished to investigate the microstructure properties and the evolution of the grain boundary changed using optical microscope. From the analysis, it showed the behavior of each type of specimen, the grain boundaries, and material properties. The heated specimen score the best properties from the fatigue failure followed corrosion specimen. The damaged in corrosion specimen is tend to crack faster because of the attack in the pitting region had damaged the grain boundary and produce starting tip that lead to the failure mechanism.
