Process annealing is carried out intermittently during the working of a piece of metal to restore ductility lost through repeated hammering or other working. Metal Science and Heat Treatment discusses fundamental, practical issues of physical metallurgy, new achievements in heat treatment of alloys, surface engineering, and heat treatment equipment. A low-temperature heat treatment used to reduce the hardness of martensite by permitting the martensite to begin to decompose to the equilibrium phases. 2.
