Abstract
A method of forming a supporting substrate for a cutting element comprises forming a precursor composition comprising discrete WC particles, a binding agent, and discrete particles comprising Co, one or more of Al, Be, Ga, Ge, Si, and Sn, and one or more of C and W. The precursor composition is subjected to a consolidation process to form a consolidated structure including WC particles dispersed in a homogenized binder comprising Co, W, C, and one or more of Al, Be, Ga, Ge, Si, and Sn. A method of forming a cutting element, a cutting element, a related structure, and an earth-boring tool are also described.
