Scientific and technical progress in our country depends largely on supplying im- portant sections of the national economy with modern materials. This may be done by improving traditional materials, as well as by developing new ones that may be used under severe temperature, stress, and velocity conditions and that have com- binations of certain physical and chemical properties. Refractory, superhard, corrosion-resistant, semiconductor, dielectric, and other materials are thus being created that will permit the development of new, highly effective tool materials, the implementation of...
