BERYLLIUM-CONTAINING ALLOYS OF ALUMINIUM AND SEMI-SOLID PROCESSING OF SUCH ALLOYS

摘要

ABSTRACT 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 find the need for introducing shear forces by utilizing itemized or ground particles of beryllium mixed with laid, particulate or liquid�s aluminum.
