摘要
研究了固溶处理温度和随后的冷却方式对Ti-600高温合金蠕变性能的影响。结果表明,为了获得最佳的抗蠕变性能,宜采用相变点以上的温度进行固溶及随后空冷的处理制度,合金在600℃、150MPa条件下进行蠕变变形,主要受晶界滑动和晶内位错的滑移和攀移所控制。
The effect of solution temperature and following cooling on creep property of Ti-600 high temperature alloy was studied. The results indicate that ,to get the best creep resistance, solution temperature at the temperature over （α＋β）/α transus temperature and followed by air cooling should be suggested. The creep strain are controlled by the sliding and the climbing of dislocation under 600℃,150MPa.
