Controllable grain-boundary displacement during recrystallization and the microrelief of a titanium surface induced by laser radiation pulses

摘要

When multipulse laser-induced recrystallization of a titanium surface occurs under the action of polarized radiation, grain growth is detected, associated with the polarization direction of the radiation. An explanation of the observed phenomenon is given, based on the effect of electron entrainment by surface plasmon-polaritons excited at the grain boundaries.
