In this paper we have studied the effect of magneto-static field on
propagation of thermal wave generated in metal by pulsed laser. In fact this interaction
generate acoustic wave in different mechanisms. However, always the common
mechanism in the interactions of laser pulse and metal is the thermo-elastic wave
generation. Applying the suitable magneto-static field on the surface of interaction of
laser pulse and metal can trap the propagation of thermal wave in thermo-elastic regime.
The physical mechanism of trapping and experimental results have investigated in this
paper. We obtained maximum reduction in 2D thermal wave propagation around
in simulation and around 5.3% by metallography. تفاصيل المقالة
