Study of thermally activated dislocation motion in AJ51 and AE42 magnesium alloys.

Abstract

Stress relaxation tests along stress-strain curves of two magnesium alloys AJ51 and AE42 are used for determining the activation volume at different temperatures. The applied stress has been separated into its effective stress and internal stress components.

The variations of the activation volume with the effective stress were examined.
