Development of P/M processing for superplastic aluminium-lithium matrix composites

This investigation involved the development of a powder metallurgical (P/M) route consisting of, powder mixing, degassing, cold isostatic pressing (CIP) and hot extrusion, for the production, principally, of a 0.8um SiCp reinforced aluminium-lithium 8090 alloy composite. Other particle sizes of rein...
