摘要: In one aspect of the invention, a wear-resistant tool is disclosed which may comprise first and second cemented metal carbide segments chemically bonded together at an interface. The first segment may comprise a first coefficient of thermal expansion (CTE) at least at its interfacial surface and the second segment may comprise a second CTE at least at its interfacial surface less than the CTE of the first segment. The first segment may further comprise a cross-sectional thickness substantially equal to or greater than a cross-sectional thickness of the second segment at the interface.
