Abstract

The evolution of grain boundaries, texture types and cracks of an extruded plate of Mg-0.4%Zn alloy during deformation by different tensile strains was investigated by means of in-situ tensile test coupled with electron backscattering diffraction (EBSD) technique in Zeiss Sigma 300 field emission scanning electron microscope. The results show that by the tensile strain from 0% to 20%, the twin boundaries of material increase gradually with the strains, the twin boundaries mainly belong to the type of {10-12} extension twin. Therewith, the twinning may bring about the variation of the texture of the alloy. During the tensile process, cracks in the Mg-Zn alloy may preferentially generate at the tips of the twins and/or initial grain boundaries, simultaneously trans-granular cracks appear in some grains with the increase of strain, finally fracture happened after the propagation of cracks.

Key words: metallic materials magnesium alloy in-situ tension twin texture crack
