研究动态应变时效对18 - 8型奥氏体不锈钢室温及高温下的抗拉及光滑弯曲疲劳强度的影响。

The of effects of dynamic strain aging on the tensile and smooth rotating strength of 18-8 type austenitic stainless steel at room and elevated temperatures were investigated.

室温冲击韧度随时效时间的延长整体下降，为韧性断裂；

Room temperature impact ductility decreased with the aging time increasing.

可使铝合金铸件从固溶温度直接快速冷却到时效温度，省去了常规工艺的室温保持。

The aluminum alloy casting can be rapidly cooled from the solutionizing temperature directly to the aging temperature, eliminating the room temperature hold of a conventional process.
