Abstract

The article deals with phase transformation in aluminum-magnesium alloys during high speed cooling after the laser action. The intermetallic precipitation growing is calculated with the reaction-diffusion model. The “shooting” method was used for analytical solution of equation for grow of spherical inclusion. Mutual influence in ensemble of precipitation is taken into account as changes of admixture concentration on “infinity”. Unification of model of precipitation ensemble development with the stochastic model of precipitation engendering and self-consistent model of laser welding allow to calculate a size distribution of inclusions in heat effected zone.
