Deformation Mechanism Maps: Their Use in Predicting Creep Behavior

A simple form of deformation mechanism map is presented which graphically illustrates the behavior of materials under steady-state creep conditions. Examples are given of maps for deformation mechanisms occurring both independently and sequentially. The use of deformation mechanism maps in the prediction of creep behavior is reviewed in detail, and an improved method is presented for estimating the total strain experienced after long-term exposure to stress and temperature.
