Abstract

A significant reduction in the dynamic modulus of elasticity of the titanium alloy OT-4 during cyclic deformation in the frequency range of 0 ÷ 25 Hz and its further stabilization at frequencies of 25 ÷ 80 Hz on the basis of studies of damped bending vibrations of a series of test samples is shown. The averaged amplitude dependence of the logarithmic vibration decrement of this alloy under tension-compression is obtained by minimizing the quadratic discrepancy between the experimental and calculated logarithmic decrements of the oscillations of the test samples.
