چکیده انگلیسی
Microstructural development under interrupted hot deformation of a cast Mg-Gd-Y-Zr alloy was investigated by optical microscopy (OM) and electron backscattering diffraction (EBSD) technology and the resultant mechanical properties were detected through tensile tests at room temperature. Ultrafine grains (UFGs) were remarkably developed under the condition of interrupted hot forging, resulting in an improvement of ambient mechanical properties. The basal texture was weakened by an effective increase of the volume fraction of UFGs under interrupted hot forging. These resulted in an improvement of tensile ductility with little or no drop in strength, i.e. the volume fraction of UFGs was raised from 30% to 70%, leading to an increase of the ambient tensile elongation from 15% to 23%.
