摘要

摘要:研究了高氮奥氏体VNS-53钢与ShKh15-ShD钢在干滑动摩擦下的摩擦技术特性。发现在薄的近表层发生应变硬化而没有马氏体转变，其结果是硬度提高90%以上。与08Kh18N10T钢相比，该钢具有较低的摩擦系数和较高的表面接触区硬度。

Structural Changes in the Surface Layers of a High-Strength Austenitic VNS-53 Steel during Wear Tests

Abstract—The tribotechnical characteristics of a high-nitrogen austenitic VNS-53 steel are studied under dry sliding friction in contact with a ShKh15-ShD steel. Strain hardening in a thin near-surface layer is found to occur without martensitic transformation, the result of which is a more than 90% increase in the hardness. This steel is found to have a lower friction coefficient and a higher increase in the hardness in the surface contact zone as compared to 08Kh18N10T steel.

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.
