Hardening (metallurgy)
open-in-new
<p>Hardening is a <a href="/facts/Metallurgical/1SANyxX4">metallurgical</a> <a href="/facts/Metalworking/eAT0Pvz2">metalworking</a> process used to increase the <a href="/facts/Hardness/PtGn6E20">hardness</a> of a metal. The hardness of a metal is directly proportional to the uniaxial <a href="/facts/Yield_stress/mrSg02gW">yield stress</a> at the location of the imposed strain. A harder metal will have a higher resistance to plastic deformation than a less hard metal. </p>
