ABSTRACT:
A composite structure is disclosed which comprises a combination of heat treatable cemented carbides and alloy steel. The carbide phase in the cemented carbide is predominantly tungsten monocarbide, or solid solutions of tungsten monocarbide and molybdenum monocarbide, of stoichiometric composition. The binder in the cemented carbide is based on heat treatable low to medium alloy steel and contains less than 1.5 percent by weight vanadium and less than 8 percent by weight chromium. A method for making the cemented carbide is also disclosed. The composite structure is formed by integral casting in steel of the preformed cemented carbide. The composite structure can be heat treated to the desired hardness and toughness properties. The primary area of application of the composites of the invention are in digger teeth for earthmoving, in mining and ore-comminution tools, and in cutter heads for deep-well drilling.
