Vibrocreep of Titanium Alloy.

The problem of titanium alloy vibrocreep at normal temperature is considered. Experimental data are presented, testifying to a substantial acceleration of creep if a harmonic component is superimposed on a constant stress. It is shown that the degree of creep intensification depends on the amplitude and does not depend on the frequency of the harmonic stress component. Theoretical generalized conclusions are drawn on the basis of the energy variant of the theory of creep and relations are proposed giving a satisfactory description of the vibrocreep process.
