The Effect of Varying Quench Rates and Heating Rates on the Aging Response of an Aluminum Powder Alloy.

Abstract

This research examines the effect of varying quench rates and the effect of varying heating rates on the aging response of powder aluminum MA87 alloy. The effect of a six-day room temperature pre-age was also considered. The results obtained are compared with results of similar research on 7075 ingot product and supplemented with electron microscopy. The results indicate little difference in terms of hardness, in the response of MA87 and 7075. This suggests that the quench sensitivity of both alloys is similar and is attributable to the same mechanism. (Author)
