The phenomenon of time-dependent plastic deformation of metallic materials under constant load at high temperatures has been documented for at least two centuries and is now termed high temperature creep. A better understanding of creep behaviour of metals and alloys is highly desirable, not only for predictions and thus more efficient exploitation of contemporary creep-resistant metallic materials, but also such an understanding may be of great help in designing new materials and their thermal and mechanical treatment. The aim of this monograph is to provide a comprehensive review of the current status of knowledge of mechanisms of high temperature creep, creep damage and creep fracture in metals and alloys. In the introductory chapters 1-6, the time dependence of creep strain, mechanical equation of state, dislocation motion in creep and dependence of creep rate on temperature, stress and some structure parameters are treated in a traditional manner, and Orowan and Bailey-Orowan equations commonly used to describe creep are mentioned.
