In this study, effect of quenching temperature on mechanical properties of Aluminum Alloy 7075 (AA7075) are investigated. Several quenching environment is tested oil (20W50), icy water (2 oC), water (25 oC), and hot water (85 oC). Mechanical properties of the materials are measured. X-ray diffraction analyses are also performed for each condition. Results indicated that properties at hot water quenching and oil quenching are found to be similar. It is concluded that oil quenching does not have significant effect on mechanical properties.
