The Thermomechanical Processing of Mg Alloys

主讲人 : Prof. Stephen Yue

Alloying additions of Nd to Mg are known to, at least, weaken the basal texture of the as worked alloy and, at best, lead to a non-basal texture. It is clear that texture weakening improves formability, but it is difficult to quantify the effect of texture weakening on formability. In a project conducted within the MagNet - NSERC (Natural Science and Engineering Council) Canadian Strategic network, a car door was successfully warm formed from ZEK sheet under conditions at which an AZ31 sheet could not be utilised. The effect of warm forming on the microstructure and texture of the ZEK is examined in order to gain insight into the mechanisms that have improved the formability compared to AZ31. At the same time, alloy variants of ZEK,  d on reducing Nd levels and eliminating Zr, have been designed and the hot deformation behaviour characterized. The goal of the alloy design work is to create alloys which have similar sheet characteristics of ‘conventional’ ZEK, assuming that this will lead to similar warm formability characteristics.
