Tungsten-Free Hard Alloys: An Analytical Review

Analysis of domestic and foreign tungsten-free hard alloys demonstrated the possibility of their application not only in cutting tools but also in the manufacture of nozzles, dies, and bushings operating in compressed and abrasive media, as well as in measuring tools and drawing dies for the fabrication of products from molybdenum, nickel, and Kovar. Higher quality of products increases the prime yield and economic efficiency. Major directions of the proposed improvements in the hard-alloy industry are specified.
