Hard Metals Production Technology and Research in the U.S.S.R. deals with the production technology and investigation of the structure and physical-mechanical properties of hard metals. One of the important elements in technical progress is the national production of hard metals. The development and introduction of highly efficient hard metals ensure that labor productivity will increase in metalworking, mining, oil, and coal industries. This book provides comprehensive information on the metallography, correct utilization, and application of hard metals that is useful in developing those industries. Topics discussed include hard alloy technology; structure and properties of hard metals; and X-ray, chemical, and spectrographic analysis of hard metals. Powder metallurgy (metal-ceramics), high-melting metals, and hard compounds are also described in this text. This publication is useful to students and researchers conducting work on the technology and production of hard metals and its raw materials.
