Abstract
Aluminum and zinc powders were mixed with various contents to magnesium alloy (AZ31) turning chips and then the powder mixtures were mechanically alloyed (MA) for various milling times. Structure of the obtained MA powder was analyzed by X-ray diffraction (XRD), for investigation of alloying process. Mg_<32>(Al,Zn)<49> phase , as called quasi-crystal (Q.C.), formed in the MA powder with Mg-(20〜40)mol%Al-(1O〜40)mol%Zn compositions. Mg_<17>Al_<12> phase also forms another Q.C. phase in MA powder with high contents of magnesium, and MgZn_2 phase also forms in MA powder with high contents of zinc.
