The aim of tempering is to achieve the best combination of mechanical properties in metals. Stress relieving is a heat treatment process that decreases stress in metals after they have been quenched, cast, normalized, and so on. Stress is relieved by heating metal to a temperature lower than that required for transformation.The Tempering of Martensite: Part One - Total MateriaAbstract: Martensite is a highly supersaturated solid solution of carbon in iron, which, during tempering, rejects carbon in the form of finely divided carbide phases. The end result of tempering is a fine dispersion of carbides in an -iron matrix, which often bears little structural similarity to the original as-quenched martensite. Martensite is a very strong phase but it is normally very brittle so it is necessary to modify the mechanical properties by heat treatment
