A special dispersion-strengthening heat treatment. By solution treatment, quenching, and aging, a coherent precipitate forms that provides a substantial strengthening effect by acting as obstacles to dislocation movement.
A heat-treating process used on martensitic stainless steels to harden them. The material is heated above its critical temperature, held at that temperature to ensure uniform temperature and then quenched in air or oil to quickly cool it.
The term as applied to soft or low carbon steels, relates to slow, gradual changes that take place in properties of steels after the final treatment. These changes, which bring about a condition of increased hardness, elastic limit, and tensile strength with a consequent loss in ductility, occur during the period in which the steel is at normal temperatures.
The changes that takes place in a steel after its final treatment at normal temperatures. The changes are slow and gradual and increase the hardness, elastic limit and tensile strength of the steel. It also results in a loss of ductility.
A process of increasing the hardness and strength by the precipitation of particles of a phase from a supersaturated solid solution alloy. The hardening cycle usually consists of heating or annealing at a temperature sufficiently high to maintain solid solution, rapid cooling or quenching to retain the supersaturated solid solution, and subsequent heating at a temperature lower than the solution anneal to effect the precipitation.
