| Abstract: | The investigation was carried out to study the effect of homogenizing annealing process on the microstructure and properties of Mg-9Gd-3Y-0.5Zr magnesium alloy and the fracture of specimens before and after homogenizing annealing was also analyzed by using of optical microscopy,X-ray diffraction analysis etc.The results show that after homogenizing annealing,the dendritic segregation is almost eliminated and the microstructure and properties of alloy are improved.The annealing temperature played a main role... |
