Thermodynamic Analysis of Compatibility of Niobium Carbide with Hadfield Steel for Cermets Development
Journal Title: Фізика і хімія твердого тіла - Year 2014, Vol 15, Issue 2
Abstract
Hadfield steel due to its high wear resistance under impact conditions is currently being considered as perspective material for using as a binder phase in carbide – steels. One of the key factors in the selection of a refractory carbide component of carbide – steels is its chemical stability with respect to metal phase. In this study, chemical interactions between niobium carbide and Hadfield steel, were analyzed from thermodynamic considerations. It is shown that niobium carbide due to its low limited solubility in manganese austenite determines the structure of the two-phase steels with hardenable binder.
