Beschreibung
Zusammenfassung:	Disclosed is a practical aluminum based alloy containing 1 to 99 weight percent beryllium, and improved methods of semi-solid processing of aluminum alloys containing beryllium. The present methods avoid molten beryllium, agitation of molten aluminum-beryllium alloys and the need for introducing shear forces by utilizing atomized or ground particles of beryllium mixed with solid, particulate or liquidus aluminum.
