Popis:	OFHC copper explosively deformed at pressures between 75 and 435 kbars is characterized by high residual stresses, compressive near the surface and tensile further in. Annealing after this deformation takes place in three some what overlapping stages. Property changes associated with these stages and possible interpretation of the effects are discussed in detail. Contrary to the annealing behavior of conventionally deformed metals, the first stage of annealing is accompanied by adecrease in density and anincrease in electrical resistivity. It is postulated that these changes are due to stress relief and microcrack growth. Also, unlike most conventionally deformed materials, the major softening stage is found to have recovery rather than recrystallization characteristics. The data in this stage are quantitatively consistent with a mechanism involving dislocation annihilation.
