Структура и текстура магния после интенсивной пластической деформации при комнатной температуре

Abstract

New methods of severe plastic deformation (SPD) have been used for the processing of magnesium at room temperature: a hydrostatic extrusion and a lateral extrusion. True strain after hydrostatic extrusion was e~3.2 and it was e~6.0 after lateral extrusion and followed cold rolling. The average grain size after SPD is about 2 microns. The main cause of the grain refinement is processes of continuous dynamic recrystallization. Mechanical properties of magnesium after SPD have been investigated.
