What are Austenite & Ferrite Stabilizing Elements in Metallurgy?

Austenite and ferrite stabilizing elements are terms used in the context of alloying elements in steel and other materials to describe their influence on the microstructure and phase composition of the material. These elements promote the formation of either the austenite phase or the ferrite phase, which are two different crystal structures in metallic materials. […]
