Abstract
Official abstract text for this publication.
A composite composed of two principal strengthening compounds and one principal cementing refractory metal that is prepared by combining a suitable binary to senary borides and/or carbides with a unitary to binary principal refractory metal is disclosed. As compared with the conventional sintered cemented carbides, the composite of the disclosure not only possess high hardness and high toughness but also has various ratios of principal components since it is not prepared with equal mole during the process.
First claim
Opening claim text (preview).
What is claimed is: 1. A composite, consisting of two principal strengthening compounds and one principal cementing refractory metal, wherein one principal strengthening compound is zirconium diboride (ZrB 2 ), the other principal strengthening compound is selected from the group consisting of TiC, VC, ZrC, HfC, WC, NbC and TaC, and the principal cementing refractory metal is tungsten (W), and the mole fraction of a total of the two principal strengthening phase compounds is 60 mol %, and the mole fraction of the principal cementing refractory metal is 40 mol %.
