摘要：
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 25-400degree celsius 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.
