摘要

摘要-一种估算铁中表面合金层固溶和沉淀硬化导致的屈服强度增量的算法,这些表面合金层是在氮化物形成金属(Cr、V、Ti、W、Mo)和氮的联合饱和过程中形成的。估计计算的输入参数是铁中的合金金属浓度,它与硬化的结构因素,即溶解氮浓度和析出氮化物的体积分数有定量关系。计算得出的硬化参数与扩散金属化(铬、钛和钒)和氮化后铠装铁改性层的显微硬度之间存在高度相关性。

Estimation of the Predicted Hardening of Iron during Surface Alloying with a Metal in Combination with Nitriding

Abstract—An algorithm for estimating the yield strength increment as a result of solid-solution and precipitation hardening of the surface-alloyed layers in iron, which are formed during combined saturation with a nitride-forming metal (Cr, V, Ti, W, Mo) and nitrogen. The input parameter for the estimating calculations is the alloying metal concentration in iron, which is quantitatively related to the structural factors of hardening, namely, the concentration of dissolved nitrogen and the volume fraction of precipitated nitrides. A high degree of correlation is found between the calculated hardening parameters and the microhardness of the modified layers in armco iron after diffusion metallization (by chromium, titanium, and vanadium) and nitriding.

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.
