Abstract

Abstract

The deformation features of a nickle-base single crystal superalloy DD3 under fatigue-creep interaction were investigated. The strain rate type fatigue-creep frature machanism map was constrcuted. The maxium stress modified equations were obtained to calculate the minium strain rate for the fixed stress conditions. It is demonstrated that the predicted values compared favourable with the observed values.
