摘要：

Creep behaviour of nickel-base solid solution strengthened NiMoCr alloy after different applied hot and cold rolling conditions was investigated. The results of creep tests showed that the creep characteristics including strain rate, fracture strain, and lifetime were greatly dependent on the plastic deformation conditions carried out prior to the creep. Failure process including crack nucleation and crack propagation was strongly dependent on grain size. Fine recrystallized structures have provided much less resistance to creep deformation compared to coarse grain size. A comprehensive study of creep deformation as a function of plastic deformation conditions of NiMoCr alloy is also presented.
