Recent Progress in the Welding of Rapidly Solidified Heat-resistant Aluminum Alloy

Heat-resistant aluminum alloy produced by rapidly solidified progress is a kind of promising aluminum al- loy.This kind of alloy has a widespread availability in aviation,space flight,ship and weapons etc.owing to its excellent me- chanical properties at elevate temperatures and low density.In this aticle,the recent year's development and latest progress in the welding of rapidly solidified heat-resistant aluminum alloy are presented,its weldabilities are analysised and the prohlems on the joining of rapidly solidified heat-resistant aluminum alloy by using GTAW,CDW,EBW,LBW,FW and braze welding are discussed.High energy density,low energy input processes such as electron beam welding and laser welding and friction weld- ing are suitable for the welding of rapidly solidified heat-resistant aluminum alloy.
