Abstract : The article is a survey of achievements in the field of materials science and problems that remain to be solved, with special emphasis on the work being done in the Ukrainian SSR. Of particular importance are new materials for solving problems in space technology. There was the unique experiment on the welding and cutting of metals in space during the orbital flight of the ship 'Soyuz-6'. Materials are of great importance for the further development of machine building, with materials created by powder metallurgy methods playing an important role. Promising materials include antifriction cermets from iron and bronze powders, wear resistant cermets based on chromium carbide alloys, high porous cermet filters, new heat resistant materials based on dislocation theory, and refractory compounds.
