Examples

Quenching is the process of cooling a high-carbon steel very quickly after heating, thus "freezing" the steel's molecules in the very hard martensite form, which makes the metal harder. Source: Internet

The steel can then be tempered by reheating to a temperature in between, changing the proportions of pearlite and martensite. Source: Internet

Internal stresses from this expansion generally take the form of compression on the crystals of martensite and tension on the remaining ferrite, with a fair amount of shear on both constituents. Source: Internet

There is no thermal activation energy for the transformation from austenite to martensite. Source: Internet

When rapidly cooled, a diffusionless (martensite) transformation occurs, in which the carbon atoms become trapped in solution. Source: Internet
