Abstract—The influence of alloying elements and heat-treatment conditions on the fracture toughness of precipitation-hardening nonmagnetic vanadium-containing steels has been studied. The causes of formation of microductile intergranular fracture in steels, the structure of which contains precipitate-free zones, are revealed. Alloying of Mn-containing steels with nickel is found to increase K_1c; the introduction of chromium in Mn–Ni steels in an amount of more than 3% leads to a decrease in K_1c. The heat-treatment conditions forming a fine-grained structure with fine VC and VN particles in an amount of 0.5–1.0 wt % is shown to provide maximum K_1c.

老化非磁性含钒钢的断裂韧性

摘要研究了合金元素和热处理条件对沉淀硬化非磁性含钒钢断裂韧性的影响。研究揭示了钢中微导晶间断裂的形成原因，钢的结构中含有无沉淀区。发现含锰钢与镍的合金化会增加 K1c；在锰镍钢中引入超过 3% 的铬会导致 K1c 下降。在 0.5-1.0 wt % 的热处理条件下形成具有细小 VC 和 VN 颗粒的细粒结构，可获得最大 K1c。

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.
