Summary

The objective of the present work is to study the effect of a semi-solid process (thixocasting) on the microstructure and creep behaviour of two Mg-Zn alloys. One of the alloys is the commercial MEZ, patented by Magnesium Elektron, and the other is an MEZ-type modified alloy with Ca-additions (ZEC). Previous studies have reported results on Mg-Zn-Ca alloys produced by rapid solidification [7] and die-casting [4], but the effect of rare earths on such alloys has not been understood. Besides, the use of semi-solid processes on aluminium free Mg-Zn alloys is until now unpopular. This work attempts to emphasize the feasibility of new forming processes on such aluminium-free systems.
