摘要
在高温多轴非比例循环加载下，对１Ｃｒ１８Ｎｉ９Ｔｉ不锈钢进行了在单轴和圆形应变路径下的循环试验、非比例循环加载历史试验以及在圆形应变路径下的应变幅值历史效应的试验。研究了非比例循环附加硬化、应变幅值历史效应、循环加载历史效应及这些效应的温度依赖性，得到了若干有意义的结果。
series of tests was performed for 1 Cr1 8Ni9Ti stainless steel under the complex uniaxial and multiaxial nonproportional cyclic, loadings at elevated temperatures. These tests in-clude the ones under uniaxial and circular strain paths,the tests of the effects of strain amplitude histories along circular strain path and the ones under nonproportional cyclic loading histories。The effects and their temperature dependenee of cyclic additional hardening,strain amplitude histories, and path histories for nonproportional cyclic loading are investigated, and some signifi-cant experimental results obtained.
