Notes:
Study about the feasibility and effect of high-energy ball milling on a specific Mg alloyunder protection medium of alcohol was presented via comparing with conventional vacuummilling. More fine particles with wider powder size distribution but more irregular shape wereshown from image analysis of the SEM pictures of the powder milled under alcohol. No obviousoxide was revealed from the X-ray diffraction of the two kinds of Mg alloy powders with limitedmilling time. And since slip induced in a preferential direction, the (002) texture was formed in theMg alloy powders at the initial stage of alcohol milling. With deformation occurred randomly, thetexture disappeared regularly. More O and Fe contaminants were introduced into the powdersmilled under alcohol according to the EDS analysis, for which the hot-pressed Mg alloy samplesfabricated with that powders exhibited lower UTS
