Abstract

A Processing map has been developed for Magnesium alloy AZ31 extruded at 450°C which revealed that the extruded rods may be further processed into components industrially at 400°C and at a strain rate of 10 s-1. If processed at lower strain rates in the vicinity of 0.1 s-1, unusual grain size variations with temperature and strain rate are observed, suggesting that grain size control will be difficult. © 2007 WILEY-VCH Verlag GmbH & Co.
