Abstract
Official abstract text for this publication.
Composites having the composition of at least one principal strengthening phase compound and one cemented phase of principal refractory metal are disclosed. The components of the strengthening phase compound can be a boride or a mixture of a boride and one or more than one carbide. In addition, the composites are obtained by smelting the principal strengthening phase compound and the cemented phase principal refractory metal in a non-equal molar ratio.
First claim
Opening claim text (preview).
What is claimed is: 1. A composite, consisting of a first principal strengthening phase compound, a second principal strengthening phase compound, and a third principal strengthening phase compound and one cementing phase of principal refractory metal, wherein the first principal strengthening phase compound is selected from the group consisting of TiB 2 and ZrB 2 , the second principal strengthening phase compound and the third principal strengthening phase compound are selected individually and independently from the group consisting of TiC, VC, ZrC, HfC, WC, NbC, and TaC, the cementing phase of principal refractory metal is selected from the group consisting of niobium, tantalum, molybdenum and tungsten, the mole fraction of a total of the first principal strengthening phase compound, the second principal strengthening phase compound, and the third principal strengthening phase compound is 60 mol %, and the mole fraction of the principal cementing refractory metal is 40 mol %, and the first principal strengthening phase compound, the second principal strengthening phase compound, and the third principal strengthening phase compound and the cementing phase of principal refractory metal are uniformly mixed by a smelting process in a water-cooled copper mold.
