Heat treatments of steels

Austenitization; austenitization

The process of heating a material to a temperature above its austenitizing temperature in order to transform it into an austenitic structure.

Carbonitriding

A thermochemical treatment process combining carburizing and nitriding, providing both increased surface hardness and improved wear resistance.

Cementation; cementation

The thermochemical process of absorbing carbon into a low-grade steel to increase its surface hardness while retaining a resilient core.

Cementite; cementite

Cementite is an intermetallic compound of iron and carbon (Fe ₃ C) found in high-carbon steels. It is hard and brittle.
