Abstract

In the presented work metal-to-liquid phase transition induced by a pulsed-laser was investigated. A numerical FDTD technique based on the solution of the coupled heat and wave equations was applied. It was demonstrated that the laser-induced melting leads to the development of a melt pool which significantly influences the generation of the elastic waves and can be utilized for localized and remote monitoring of the laser pulse-induced solid-to-liquid phase transition in refractory metals preset in harsh environments.
