Abstract: In seeking to understand and quantify the creep and creep fracture properties of metals and alloys, many unresolved problems have resulted from the use of power‐law concepts for mechanistic studies and standard parametric procedures for estimation of long‐term engineering design data. However, the theoretical and practical limitations of these traditional approaches can be overcome by methodologies involving analysis of creep curve shapes. Even so, much new knowledge is required to develop stress/strain/time/temperature relationships which accurately define the behaviour of creep‐resistant alloys under the complex non‐steady operating conditions encountered in service.
