Abstract
Official abstract text for this publication.
A composite metal where a phase of particles of solid solution is uniformly dispersed in a Cu phase, the solid solution containing a solid solution of a heat resistant element selected from Mo, W, Ta, Nb, V and Zr and Cr. The composite metal is provided to contain: 20-70% of Cu; 1.5-64% of Cr; and 6-76% of a heat resistant element by weight relative to the composite metal, wherein a remainder is comprised of inevitable impurities. In the composite metal, the particles of the solid solution, contained in the composite metal, are provided to have an average particle diameter of not larger than 20 μm and to uniformly disperse in the Cu phase with an index of the dispersion state of not higher than 1.0.
First claim
Opening claim text (preview).
The invention claimed is: 1. A composite metal where a phase of particles of solid solution is uniformly dispersed in a Cu phase, the solid solution comprising a solid solution of a heat resistant element selected from Mo, W, Ta, Nb, V and Zr and Cr, the composite metal comprising: 20-70% of Cu; 1.5-64% of Cr; and 6-76% of a heat resistant element by weight relative to the composite metal, wherein a remainder is comprised of inevitable impurities, wherein the particles of the solid solution, contained in the composite metal, has an average particle diameter of not larger than 20 μm and uniformly disperses in the Cu phase with an index of the dispersion state of not higher than 1.0. 2. An electrode comprising a composite metal as claimed in claim 1 .
