This study examines a model of two-component metal powder mixtures melting under laser heating. A mixture consisting of components with high and low melting temperatures is studied. Within the suggested model, several numerical experiments have been carried out and their results analyzed. The process of the propagation of the melting and the solidification fronts has been investigated. A conclusion and a criterion have been obtained for the melting front of the powder mixtures to be non-evolutionary in the gravity field.
