The P92 steel is a steel sort being used for main steam pipelines of ultra-supercritical units at present, its creep rupturelife has widely drawn close attention.
P 92钢是目前超超临界机组主蒸汽管道的应用钢种，其蠕变断裂寿命被广泛关注。

The recycle times has little effect on the fracture mechanism and tensile properties at high temperature, but reduces slightly the stress-rupturelife of revert K446 alloys.
返回次数对K446合金高温断裂特征和高温拉伸性能没有明显影响，但降低持久性能。
