austeniteerimise
Austeniteerimise, or austenitisation, is a heat treatment step used in iron-based alloys, especially carbon and alloy steels, in which the material is heated into the austenite stability region to form homogeneous gamma-iron (austenite). The purpose is to dissolve alloy carbides, homogenize composition, and produce a uniform austenitic phase that can be transformed by quenching or further heat treatment.
Procedure and conditions: The steel is heated to a temperature above its upper critical temperature, typically
Outcomes and considerations: The resulting austenite can be rapidly cooled (quenched) to form martensite or bainite,
Applications: Austenitising is a common preparatory step in hardening and strengthening heat treatments, as well as
