High strain rate superplasticity in friction stir processed Al–Mg–Zr alloy

Al–4Mg–1Zr extruded bar was subjected to friction stir processing (FSP), resulting in generation of a fine microstructure of 1.5 μm grain size. Superplastic deformation behavior of FSP Al–4Mg–1Zr alloy was investigated in strain rate range of 1×10 −3 to 1 s −1 and temperature range of 350–550 °C and...
