Abstract:
The effect of impurities of light elements C, N, O on the velocity of motion of the crystallization front in fcc metals Ni and Ag was studied by the method of molecular dynamics. The dependences of the crystallization rate on the concentration of impurities are obtained. It is shown that the presence of impurities leads to a significant slowdown in the velocity of motion of the crystallization front in metals. Braking of the crystallization front by the impurity atoms is associated with the local deformation of the crystal lattice that they cause, and, as a rule, the greater this deformation, the stronger the impurity atoms inhibit the crystallization front.
Keywords:
molecular dynamics, metal, crystallization, impurity, crystallization front.
