Effects of alloying on nitriding behavior and fatigue performance of medium carbon bar steels
Nitriding is a surface hardening technique commonly applied to transmission gears for improved fatigue resistance. Steel alloys used for nitrided transmission components often do not have optimized compositions and thermal processing routes to maximize fatigue performance after nitriding. Furthermore, significant cost and processing time savings could be realized if nitriding could be performed without first heat treating to form tempered martensite. Additions of vanadium (V) and silicon (Si) to a series of experimental medium carbon steels were evaluated in order to improve fatigue performance ...
