• Hysteresis of grain boundary mobility of tilt [1010] grain boundaries in zinc

Abstract

The hysteresis of the temperature dependence of grain boundary mobility due to grain boundary phase transitions has been studied. It was found experimentally that the dependence of grain boundary mobility on the inverse annealing temperature was nonlinear and did not coincide during heating and cooling. The curvilinear segment formed by temperature dependences of mobility at heating and cooling is considered as a hysteresis loop.
