通过对Mg-Gd-Y耐热镁合金进行不同温度、不同的时间的固溶处理,研究了该合金在不同条件固溶过程中的微观组织的变化。结果表明:530℃×4 h的固溶效果最好。
The microstructure of the Mg-Gd-Y heat-resistant magnesium alloy was studied by solution heat treatment at different temperatures and different times. The results show that the solution treatment at 530 ℃ × 4 h is the best.
