Record superplastic ductility in a magnesium alloy processed by equal-channel angular pressing

Record superplastic ductility in a magnesium alloy processed by equal-channel angular pressing
Record superplastic ductility in a magnesium alloy processed by equal-channel angular pressing
The Mg-5.5 % Zn-0.5 % Zr alloy exhibits large superplastic elongations after processing by Equal-Channel Angular Pressing and these are strongly dependent on the number of passes through the die. Grain refinement improves the elongations up to a peak of 3050 % after 2 passes but grain growth limits ductility after larger numbers of passes.

Abstract

The Mg-5.5 % Zn-0.5 % Zr alloy exhibits large superplastic elongations after processing by Equal-Channel Angular Pressing and these are strongly dependent on the number of passes through the die. Grain refinement improves the elongations up to a peak of 3050 % after 2 passes but grain growth limits ductility after larger numbers of passes.
