Abstract
review of the literary research results is presented, on the basis of which it is seen that the algorithm of modelling the structural composition of the metal, prediction of its mechanical properties should contain a description of reactions on the formation and development of dendritic structure. The models built on the description of reactions of γ-α-transformation do not provide the possibility for evaluation of the process of the structure formation as an integral complex – from the beginning of dendrites nucleation to the final composition of the microstructure. The results of the studies that have been performed in recent decades describing the impact of refractory compounds inoculation to melts of low-alloyed steels and, in particular, welding pool, on the development of nucleation processes, growth and decay of dendrites during metal crystallization. The abilities of the influence of inoculants on the primary structure formation are shown in order to improve the properties of welds metal. 22 Ref., 3 Fig.
