Abstract

PURPOSE: To improve especially the high temperature strength, of the hard alloy constituted of tungsten carbide as the base including the specified amount of metal of the iron family as the bond phase, by specifying the average crystal grain size of the bond phase at above the normal value, against the content of the bond phase.
CONSTITUTION: At the sintered hard alloy constituted of WC as the base including single or more than two of metal of the iron family as the bond phase by 3W30 wt%, the average crystal grain size of the bond phase against the content of the bond phase is specified at the upper region than the curve in the graph. This alloy is excellent in the high temperature strength, and is suitable for the cutting tool, the wear resisting tool, and the impact resisting tool.
