Critical review of mechanism of superplastic deformation in fine grained metallic materials

Abstract:

Superplastic deformation is arguably the most dramatic and direct illustration of the influence of grain boundaries on the mechanical properties of fine grained metals. Stable tensile elongations in excess of 1000% can be attained under suitable conditions, and microstructural observations show that most of this strain is a direct result of grain boundary sliding, with only transient accommodation strains taking place within the grains. The aim of this paper is to provide a critical review of...
