Heat treatment is a generic term covering a variety of processes carried out on metals and metallic alloys to modify their properties in some way. Such procedures, as the name suggests, are aimed at heating the material to high temperature and then cooling it. Sometimes the cooling occurs normally by removing the heat source and allowing the part slowly to return to ambient temperature; at other times the treatment may call for the part to be quenched in some suitable liquid while still hot. The aim is always to produce properties suitable for a particular requirement. The principle is that the atomic structure of the material can be modified by a controlled heating and cooling process. Typical characteristics which are affected by heat treatment are hardness, strength, ductility and electrical characteristics. Heat treatment may be necessary to prepare a metal for machining.
