Abstract—The problems of forming the structure of heterogeneous powder materials of tool plates are considered. A high-quality powder material is found to be produced as a result of creating a more equilibrium structure in the form of rounded solid-phase particles, which have a high adhesion strength with the minimum free (surface) energy of the interatomic interaction forces in the solid components of alloys. When a structure of powder alloys with regular-shape particles (faceted, rounded) is formed, the most important properties of hard alloys are found to increase, which eventually ensures such stable performance indicators of parts as wear resistance, fatigue strength, creep, and impact toughness.
期刊介绍：
Russian Metallurgy (Metally) publishes results of original experimental and theoretical research in the form of reviews and regular articles devoted to topical problems of metallurgy, physical metallurgy, and treatment of ferrous, nonferrous, rare, and other metals and alloys, intermetallic compounds, and metallic composite materials. The journal focuses on physicochemical properties of metallurgical materials (ores, slags, matters, and melts of metals and alloys); physicochemical processes (thermodynamics and kinetics of pyrometallurgical, hydrometallurgical, electrochemical, and other processes); theoretical metallurgy; metal forming; thermoplastic and thermochemical treatment; computation and experimental determination of phase diagrams and thermokinetic diagrams; mechanisms and kinetics of phase transitions in metallic materials; relations between the chemical composition, phase and structural states of materials and their physicochemical and service properties; interaction between metallic materials and external media; and effects of radiation on these materials.
