Abstract:
Among the products of electronic components, intended for the development and production of the vacuum, and discharge of semiconductor devices, a significant number of them are made from powders of metals and dielectrics, as well as in the form of nanoparticles and multilayer nanostructures. An important part of these products constitute a heat sink elements derived from pseudo-type molybdenum-copper and tungsten-copper. This paper examines the reasons for the backlog parameter pseudoalloys materials principally by domestic production potential. It describes the current method of mass production pseudoalloys materials as well as the method used in this study. Showing and illustrated defects appear in this method. On the causes of these defects in terms of the physical phenomena occurring in the manufacture of pseudoalloys. It also includes the principle of calculating the minimum possible porosity when using this method. The data on the Exploration of detailed physical and technological factors affecting the quality of the heat-diverting elements derived from the powder by its rolling and heat treatment.
