Influence of strain rate on deformation behaviour of an AX52 alloy processed by equal channel angular pressing (ECAP)

Cast AX52 magnesium alloy with Al and Ca was processed by equal channel angular pressing (ECAP) using A route and 1-8 passes. The light and electron microscopy revealed substantial microstructure refinement. Al2Ca eutectics are the typical feature of the microstructure. The ECAP procedure disintegrated eutectic particles. Miniaturised samples, cut from the ECAPed bulks so that the samples tensile axis was parallel to the extrusion direction,...
