تأثير متغيرات التعتيق الاصطناعي على مقاومة الشد والبنية المجهرية لسبيكة الألمنيوم 7075
Abstract
In this research, we studied the effect of change in artificial aging time and temperature on tensile strength and Microstructure for 7075 aluminum alloy, where samples of aluminum alloy 7075 were treated with artificial aging at different temperatures are 120 ° C, 160 ° C and 200 ° C for 0.5, 1.5, 3, 18, 48 hours. When the 7075-aluminum alloy was artificially aged in of 120 ° C and 160 ° C, the values of ultimate tensile strength (UTS) of the alloy were higher than when it was aged in 200 ° C. By increasing of artificial aging time, the UTS of 7075 aluminum alloy increased, when the aging temperature was 120 ° C or 160 ° C, while the UTS decreased when the aging temperature was 200 ° C. This is due to changes in the microstructure, grain size, and precipitating phases such as MgZn2
