Abstract
The creep of PT-3V titanium alloy and its welded butt-joint (PT-2V is used as the additive material) is investigated on cylindrical specimens. In considered range of cyclic stress amplitudes, the cyclic preloading is shown to result in 11% increase of the cyclic creep limit of alloy and 19% increase of the static creep limit of weld material. Duration of the cyclic preloading takes 5·104 cycles on a frequency of 35 Hz. The observable variation of mechanical properties is explained by positive effect of vibration treatment on stabilization of sizes and shapes of articles.
