PHYSICAL MODEL ABOUT LASER IMPACT ON METALS AND ALLOYS

In this ar-tic-le we pre-sent our physi-cal mo-del for in-ter-ac-ti-on of la-ser ra-di-a-ti-on with me-tals and al-loys thro-ugh struc-tu-ral chan-ges, mel-ting and va-po-ri-zing. We de-scri-be the in-ter-ac-ti-on of la-ser ra-di-a-ti-on with ma-te-ri-als, ki-ne-tic pro-cess of energy tran-smit-ting from free elec-trons to the crystal lat-ti-ce and pro-pa-ga-ti-on of he-at and the pro-ces-sing zo-ne. We con-si-der in-flu-en-ce of op-ti-cal and ther-mal pro-per-ti-es over ex-plo-ring pro-cess as they chan-ge with tem-pe-ra-tu-re and in the pre-sen-ce of mix-tu-res.
