| Achoimre: | Title screen The laser melting technique when new materials and details are synthesized is characterized by numerous factors affecting the result. To investigate the shrinkage dynamics and temperature evolution the model of laser melting of Ti-Nb-powder layer located on the Ti-substrate is suggested in this paper. The melting is described using two-phase zone theory. The properties change (heat capacity, thermal conductivity, reflection factor) together with porosity evolution is taken into account. It was detected that thermal regime of laser melting significantly depends on properties evolution and on summary heat losses from the area of laser beam action.
