Cyclic Strength of Nonmagnetic Vanadium-Containing Aging Steels
Abstract—The influence of alloying elements and surface treatment (turning, grinding, shot peening, roller burnishing) on the cyclic strength of precipitation-hardening nonmagnetic vanadium-containing steels has been studied. Significant strengthening of the steels is achieved due to the precipitation of fine VC, VN, M6C, and NiAl particles at a small interparticle distance (0.05–0.10 μm), which hinders fatigue crack nucleation and growth. Fine carbide and nitride particles mainly increase the cyclic strength at room temperature. At cryogenic temperatures, deformation twinning plays a significant role in the resistance to fatigue failure.
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.
