A technology for producing refractory pseudo-alloys of molybdenum-copper and tungsten-copper systems, which are used as electrically conductive and heat-conducting products in various electronic devices, is optimized based on calculation, model and experimental methods. The optimization of the technique for producing pseudo-alloys of various compositions is based on a method for controlling the electrical characteristics of samples during the infiltration of a porous refractory skeleton with a liquid phase having high electrical conductivity. The proposed method establishes the dependence of the porosity of the refractory skeleton in the process of infiltration on its electrical conductivity and allows you to accurately record the moment of completion of the complete filling of the capillaries in the porous skeleton with a liquid component. This must be taken into account during the final cooling upon receipt of non-porous pseudo-alloys with high stability of physical properties. Modeling of a new method for producing non-porous pseudo-alloys was carried out on the Cu-Mo system.
