An Introduction to Nitriding - ASM International
The secret of the nitriding process is that it does not require a phase change from ferrite to austenite, nor does it require a further change from austenite to martensite. In other words, the steel remains in the ferrite phase (or cementite, depending on alloy composition) during the complete proce-dure.

Introduction to Surface Hardening of Steels
Case depth of carburized steel is a function of carburizing time, the steel chemistry, and available carbon (carbon potential) at the sur-face. When prolonged carburizing times are used for deep case depths, a high carbon poten-tial produces a high surface-carbon content, which may thus result in excessive retained austenite or free carbides.
