SUPERPLASTICITY OF ALUMINIUM ALLOYS

摘要

Superplastic behaviour has been demonstrated for a number of aluminium base alloys, and the related ductilities observed are frequently in excess of 600 percent and occasionally as high as 1500 percent [2]. The researches that have been devoted to development of different aluminium alloys alloys designed for superplasticity and comercial alloys that have been specially thermomechanically processed to be superplastic. The paper reviews briefly the aluminium alloys, the superplastic properties of these and the methods for grain refinement.
