Improvements in ductility were due to a significantly improved homogenization of the microstructure during FS processing. The FSP technique is amenable to produce ductile, very high specific strength aluminum alloys, such as the Al-Ti-Cu and Al-Ti-Ni. 关键词: Aluminum alloys;Friction welding;Strength of materials;Mechanical alloying;Hot isostatic pressing;Ductility;Metallographic microstructure;Billets (metal bars);Intermetallics;Friction stir processing
