Jnhmicro-texture of AZ31 Magnesium Alloy in Situ Tracking During Compressing Deformation

Abstract

Micro-texture evolvement mechanism of AZ31 magnesium alloy during compressing deformation had been studied in situ tracking method by EBSD(Electron backscatter diffraction). The micro-texture at same observation areas, which compressed three times continually at different deformation degree, had been investigated. The results presented that the micro-texture of AZ31 magnesium alloy rolling state is typical (0001) basic texture. When deformation degree was 11% and the temperature was 170ଌ, grains orientation changed remarkably, and most grains had been twined fully and little grains twined partially. The initial basical rolling texture weakened gradually, and twined grains tropism accorded with $ \lt 10\bar 10 \gt $ and 86.3° $ \lt \bar 12\bar 10 \gt $ orientation.
