A STUDY ON AGING TREATMENTS FOR ALLOY 2195

Abstract

Abstract: Effects of various aging treatments on mechanical properties and microstructure of alloy 2195 have been investigated. The experimental results showed that a promising combination of strength and ductility was achievable under T8 temper. The lower aging temperature reduced subgrain-or grain-boundary T1 precipitation and favored uniform dispersion of T1 phases, resulting in better strength and ductility. Prior deformation improved aging strength with promising ductility. Pre-aging after prior deformation had little effect on the age-hardening behavior of alloy 2195.

Key words: Al alloy 2195, aging, mechanical property, microstructure
