Abstract—The main features of the formation of Cr₃C₂–Ti and SiC–Ti cermets during explosive pressing of powder mixtures on a steel base are considered. Strong interfaces between a carbide (Cr₃C₂ or SiC) and titanium are found to form when the heating temperature of a powder mixture during shock-wave compression reaches (0.35–0.4)T_m, where T_m is the melting temperature of the carbide. Here, the chemical compositions of the alloy components do not change, no element redistribution between phases occurs in macrovolumes, and the hardness reaches its maximum.

碳化物和钛粉混合物的爆炸压制生产的陶瓷

摘要：研究了在钢基上爆炸压制粉末混合物形成Cr3C2-Ti和SiC-Ti陶瓷的主要特征。当粉末混合物在冲击波压缩过程中的加热温度达到（0.35-0.4）Tm时，碳化物（Cr3C2或SiC）与钛之间形成强界面，其中Tm为碳化物的熔化温度。此时，合金组分的化学成分不发生变化，大体积内元素不发生相间再分布，硬度达到最大值。

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.
