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.

粉末硬质合金刀具切割板中颗粒的球形化

摘要--考虑了工具板异质粉末材料结构的形成问题。研究发现，要生产出高质量的粉末材料，就必须以圆形固相颗粒的形式形成较为平衡的结构，这种结构具有较高的粘附强度，合金固体成分中原子间相互作用力的自由（表面）能最小。当粉末合金形成具有规则形状颗粒（切面、圆形）的结构时，硬质合金最重要的性能就会增加，最终确保零件具有稳定的性能指标，如耐磨性、疲劳强度、蠕变性和冲击韧性。

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.
