Micro-Tensile Behavior at a High Temperature in an AZ31 Magnesium Alloy Processed by ECAP

Article Preview

Abstract:

A magnesium AZ31 alloy was processed by ECAP at a temperature of 473 K using a die with a channel of 110^o. The results show that the grain size was reduced from 5.4 μm to ~1.0 μm. Micro-tensile tests of the AZ31 alloy were conducted using as-received and ECAP-processed AZ31 alloy at a temperature of 473 K. The ductility of the AZ31 alloy can be improved significantly after ECAP processing at high temperature, which demonstrates a potential application in micro-forming technology for the UFG AZ31 alloy.
