COMPOSITE CEMENTED CARBIDE ROTARY CUTTING TOOLS AND ROTARY CUTTING TOOL BLANKS
Abstract:
Composite articles, including composite rotary cutting tools and composite rotary cutting tool blanks, and methods of making the articles are disclosed. The composite article includes an elongate portion. The elongate portion includes a first region composed of a first cemented carbide, and a second region autogenously bonded to the first region and composed of a second cemented carbide. At least one of the first cemented carbide and the second cemented carbide is a hybrid cemented carbide that includes a cemented carbide dispersed phase and a cemented carbide continuous phase. At least one of the cemented carbide dispersed phase and the cemented carbide continuous phase includes at least 0.5 percent by weight of cubic carbide based on the weight of the phase including the cubic carbide.
