Abstract
Comparative analysis of thermodynamic properties of coarse grain and bulk nano-crystalline titanium prepared by the method of severe plastic deformation (SPD) allowed the explanation of nano-crystalline state as specific transformation in the grain boundary defect ensemble — structural-scaling transition. By the analogy with the first kind of phase transition the anomaly of mechanical energy absorption under transition to the fine grain state was predicted theoretically and supported experimentally under realization of cyclic loading of coarse grain and fine grain titanium using the high resolution infra-red camera.
