The application of high pressure to metals and alloys can cause changes to their structures and mechanical properties observed subsequently. The nature and magnitude of these changes depends primarily on such factors as the type of material and its initial structure, the nature and magnitude of the pressure applied (static or dynamic), the types of phase transformation or precipitation induced by changes in pressure at constant temperature (abaric transformation) or in temperature at constant pressure (athermal transformation and quenching followed by isothermal transformation), and the accidental introduction of plastic distortion during the pressure cycle.
The contributions and interrelationships of these various factors are discussed for different metals—in particular, iron and some alloys of iron. Attention is given to the effects of crystalline anisotropy, changes in phase equilibria and reaction kinetics, quasi-hydrostatic pressure conditions, and shock-induced imperfections.
