Abstract

The deformation behavior and mechanisms of superplastic flow in two microduplex stainless steels have been studied at ∼0.7T_m. The two steels differed in initial grain size by a factor of 3. Both steels exhibited solute-drag-controlled grain boundary sliding in a high temperature γ+δ phase field. In a lower temperature γ+σ phase field, the fine-grained steel (L̄ = 5 μm) exhibited climb-controlled grain boundary sliding and the coarser-grained steel (L̄ = 15 μm) exhibited solute-drag-controlled slip creep.
