摘要

"The body of cemented carbide sinter, method for producing the same, and the use of cemented carbide sintered body.A sintered cemented carbide body (for example, a cutting tool) and a method of producing the same.The body of cemented carbide sinter includes tungsten carbide, a binder phase of at least one metal of the group of iron or an alloy thereof, and one or more solid solution phases.Each of the solid solution phases has at least one of the carbides and carbonitrides of a combination of zirconium, niobium and tungsten.The method includes the steps of providing a mixture powder containing tungsten carbide powder, a metal binder comprising at least one metal of the group of iron or an alloy thereof,And at least one of the carbides and carbonitrides of both zirconium and niobium carbides or carbonitrides including a powder of zirconium and niobium, forming a green compact of the mixture of powder.The vacuum or sinter and sinter - hip said green compact at a temperature of 1400 to 1560 198 C.
