Effect of Dynamic Non-Equilibrium Processes on Mechanical Properties of α + β Titanium Alloys
Abstract
Using the example of tests of two-phase sheet high-strength titanium alloys VT23 and VT23M with different initial structure and phase composition, the main regularities in the change of mechanical properties due to additional force impulse loading at room temperature are established. It is shown that dynamic non-equilibrium processes (DNP), which are realized in alloys under a given loading type, can lead both to a significant improvement of mechanical properties during subsequent static stretching, and to their deterioration. The factors influencing this process are analyzed.
