Effect of Thermomechanical Treatment Modes on the Concentration and Diffusion Characteristics of Interstitial Atoms (C, O, N) and Elastic (Young's) Moduli in Vanadium and Vanadium Alloys (V–4Cr–4Ti, V–W–Cr, V–Ta–Cr–Zr)

The elastic (Young's modulus) and relaxation (amplitude-independent internal friction) properties of metallic V and its low-activated alloys (V–4Cr–4Ti, V–W–Cr, V–Ta–Cr–Zr) have been studied by dynamic mechanical spectroscopy in the low-frequency range (0.5–30.0 Hz) and in the temperature range of 25–400°C in their annealed states. The solid-solution concentrations and diffusion characteristics (diffusion activation energies) of the C, O, N interstitial atoms have been determined. The changes in the obtained characteristics in comparison with their values for the cold-deformed states of the investigated materials have been determined. [ABSTRACT FROM AUTHOR]
