摘要

对经过各种热处理的21NKMT马氏体时效钢在干滑动摩擦条件下进行了金相、硬度学研究和磨损试验。结果表明，淬火和单次时效试样的磨损率最低，而双次时效试样的硬度最高，达到630 HV。21NKMT钢的双重时效和过时效导致磨损率提高12-33%。

Study of the Characteristics of Maraging Steel under Tribotechnical Loading

Metallographic and durometric studies and wear tests of 21NKMT maraging steel are carried out under dry sliding friction conditions after various types of heat treatment. It is established that the samples subjected to quenching and single aging have the lowest wear rate, while the samples subjected to double aging have the highest hardness of 630 HV. The double aging and overaging of 21NKMT steel lead to a 12–33% increase in wear rate.

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.
