Abstract:
A macroscopic composite sintered powder metal article including a first region including cemented hard particles, for example, cemented carbide. The article includes a second region including one of a metal and a metallic alloy selected from the group consisting of a steel, nickel, a nickel alloy, titanium, a titanium alloy, molybdenum, a molybdenum alloy, cobalt, a cobalt alloy, tungsten, and a tungsten alloy. The first region is metallurgically bonded to the second region, and the second region has a thickness of greater than 100 microns. A method of making a macroscopic composite sintered powder metal article is also disclosed, herein. The method includes co-press and sintering a first metal powder including hard particles and a powder binder and a second metal powder including the metal or metal alloy.
