Abstract

The effects of homogenizing annealing process on the microstructures and properties of Mg-Gd-Y-Zr magnesium alloy were investigated and the fracture of specimens before and after homogenizing annealing was also analysized by optical microscopy，X-ray diffraction analysis etc．The results show that after homogenizing annealing，dendritic segregation is almost eliminated and the microstructures and properties of alloy are improved. The annealing temperature played a main role in homogenizing of Mg-Gd-Y-Zr alloy. The optimal homogenizing annealing process is at 480°C for 8h．
