ABSTRACT:
Disclosed is a practical magnesium based alloy containing 1 to 99 weight % beryllium and an improved method of semi-solid processing of magnesium alloys containing beryllium. The present method avoids agitation of molten alloys and the need for introducing shear forces by utilizing atomized or ground particles of beryllium mixed with solid, particulate or liquidus magnesium.
