| description | A method of forming an impregnated cutting structure for an earth-boring tool comprises providing a powder mixture comprising diamond particles and a metal binder in a press and subjecting the powder mixture to a pressure greater than about 4.0 GPa and a temperature greater than about 1,200° C. to densify the powder mixture and form an impregnated cutting structure comprising the diamond particles dispersed in a continuous phase comprising the metal binder, wherein the impregnated cutting structure is substantially free of diamond-to-diamond bonds and of carbides. Related methods of forming an earth-boring tool and a related earth-boring tool including the impregnated cutting structure are also disclosed. |
