Influence of Microporosity Morphology on Hot Compression Behavior of 6063 Alloy

Abstract:

The influences of microporosity morphology on the flow stress behavior of 6063 alloy were investigated by isothermal compression test at 300°C-500°C and strain rate of 0.01-10s^-1. After 60% compression, the area fraction of microporosity of sample having lage microporosity decreases obviously. The flow stress increases with increasing strain rate and decreasing temperature. The flow stress stress behavior of 6063 alloy during hot compression can be described by a Zener-Hollomon parameter including Arrhenius item. The increasing of area fraction of microporosity decreases the deformation activiation energy Q.
