Synthesis and characterisation of new sputtered metastable carbides

Abstract

This paper describes part of a work carried out to develop new ternary M-M1-C systems (M=metal of the Groups IV-VI and M1=Group VIII element) by sputtering. The results obtained in this study on Ti-Fe-(C) and Mo-Fe-(C) systems showed that, depending on the type and content of iron, the obtained materials are structurally metastable, formed either by structures with enlarged solubility domains or amorphous structures. The amorfisation was verified in the Ti-Fe and Mo-Fe-C systems, as a result of the introduction of iron. The Ti-Fe-C system shows better resistance to amorphisation than the Mo-Fe-C system.
