The evolution of dispersoids is an important aspect in the development of microstructure in most
commercial precipitation hardening alloys.
Therefore many investigations have been made about the effect of dispersoids on the softening behavior of Cu-Fe-P alloys [1-7].
On the other hand, fine particles with a diameter less than 0.1μm retard recrystallization and grain growth in alloys.
These particles are identified as Fe-P intermetallic compounds or Fe particles by EDS and the average size of them is approximately 1.2μm.
The ratio of the amounts of dispersoids for each particle size in Cu-Fe-P alloys was evaluated quantitatively by extracted residue analysis method.

But there is little published literature on Magnisium alloys produced by SEED process Despite the SEED rheo-diecast Mg-Gd-Y-Zn-Zr alloy reported by Chang et al. [5].
Thixomolding is a widely used semisolid technology for Mg-Al series alloys such as AZ91[7].
The Mg-RE alloys represented by Mg–Gd-Y system have outstanding mechanical properties at both high temperature and room temperature.
The aim of this work is to study the microstructure and mechanical properties of Mg-12Gd-3Y-1Zn-0.4Zr alloy prepared by SEED technology during solution and ageing process. 2.
