A process of aging that increases hardness and strength and ordinarily decreases ductility. Age hardening usually follows rapid cooling or cold working.
Material hardening by aging
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.
An aging process that increases hardness and strength. Ordinarily ductility decreases. Usually rapid cooling or cold working.
A process of aging that increases hardness and strength and ordinarily decreases the ductility of metals.
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.
Hardening by aging, usually after rapid cooling or cold working.
An aging process that results in increased strength and hardness.
The hardening of steel induced by ageing.
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.
Martensitic stainless steels are hardened by heating above their critical temperature, holding them at heat to insure uniform temperature, and cooling them rapidly by quenching in air or oil.
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.
Heating a metal to a uniform heat and then rapidly cooling it with air or oil to harden it.
