Abstract: 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.

Key words: high temperature, nonproportionalloading, temperature dependence
