Abstract
The effect of aging pre-treatment on the compressive deformation of a commercial WE54 alloy is studied. Age hardening treatments were performed at 170 °C, 250 °C and 300 °C. Compression testing was then carried out for the peak aged samples at temperatures between ambient and 450 °C. Twinning dominated the deformation at lower temperatures for all initial microstructures. This behaviour was replaced by slip dominated flow when the temperature was raised. The temperature of the transition from twinning to slip dominated flow was only mildly sensitive to the pre-treatment. It is also evident that dynamic recrystallization is retarded in this alloy.
