Cermet cutting tool - contg carbide and tungsten in structure with no binder metal

摘要

Compsn. range is defined by the area on the ternary diagram M, W, C, (where M is Hf, Zr, Ti) in the region M40W30C30-M24W57C25-M25W60C15-M15W70C15. Compsn. forms a two phase microstructure with a metallic matrix contng. a uniformly dispersed mono-carbide phase. Compsn. is free from added binder metal.
