Abstract

The study investigated the creep behaviour of a nickel based solid solution strengthened NiMoCr alloy after different applied hot working conditions. Creep tests were conducted at a stress level of 160 MPa and a temperature of 710°C. The results showed that creep characteristics, greatly depend on the initial hot working conditions (heating temperature and degree of deformation in the process) and annealing time carried out prior to creep. Failure mechanisms including crack nucleation and crack propagation strongly depended on the grain boundaries. Fine recrystallized structures had provided much less resistance to creep deformation.
