摘要

确定了初始塑性拉伸变形（εpd = 9.5 ~ 26%）对0.3和0.8 mm厚VNS9-Sh TRIP钢带低周疲劳性能、相组成和残余应力的影响。随着εpd的增大，两种厚度的条带的LCF电阻均减小。与静态拉伸在马氏体中产生压应力不同，循环加载导致马氏体中形成拉应力。

Effect of Preliminary Deformation on the Low-Cyclic Fatigue Characteristics, Phase Composition, and Residual Stresses of VNS9-Sh TRIP Steel

The influence of preliminary plastic tensile deformation (ε_pd = 9.5–26%) on the low-cyclic fatigue (LCF), phase composition, and residual stresses of 0.3- and 0.8-mm thick VNS9-Sh TRIP steel ribbons is determined. The LCF resistances of the ribbons of both thicknesses are shown to decrease as ε_pd increases. Cyclic loading is found to lead to the formation of tensile stresses in martensite, unlike static tension inducing compressive stresses in martensite.

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.
