A review and analysis of investigations in a variety of areas relevant to creep plasticity. These areas include five-power-law creep, sometimes referred to as dislocation climb-controlled creep in metals, alloys & ceramics, viscous glide or Three-Power-Law creep in alloys, diffusional creep, Harper-Dorn creep, superplasticity, second-phase strengthening, and creep cavitation & fracture.
