Hardened steel. The term hardened steel is often used for a medium or high carbon steel that has been given heat treatment and then quenching followed by tempering. The quenching results in the formation of metastable martensite, the fraction of which is reduced to the desired amount during tempering. This is the most common state for finished ...
Hardening (metallurgy) Hardening is a metallurgical metalworking process used to increase the hardness of a metal. The hardness of a metal is directly proportional to the uniaxial yield stress at the location of the imposed strain. A harder metal will have a higher resistance to plastic deformation than a less hard metal.
Differential hardening is a method used in heat treating swords and knives to increase the hardness of the edge without making the whole blade brittle. To achieve this, the edge is cooled faster than the spine by adding a heat insulator to the spine before quenching. Clay or another material is used for insulation.

The stress at initial yield is σ0. Work hardening, also known as strain hardening, is the process by which a material's load-bearing capacity (strength) increases during plastic (permanent) deformation. This characteristic is what sets ductile materials apart from brittle materials. [1] Work hardening may be desirable, undesirable, or ...

In metallurgy, solid solution strengthening is a type of alloying that can be used to improve the strength of a pure metal. [ 1 ] The technique works by adding atoms of one element (the alloying element) to the crystalline lattice of another element (the base metal), forming a solid solution. The local nonuniformity in the lattice due to the ...
