THE RELATIONSHIP SHAPE OF THE CRYSTALLIZATION FRONT WITH THE STRUCTURE OF HEAT-RESISTANT ALLOYS IN THE PROCESS OF CRYSTALLIZATION

In the article, the analysis of the impact of the criterion of concentration of hypo-thermia on the shape of the front crystallization, in an attempt to retire the ratio between axial and radial gradients with crystallization under which dendrites symmetric relative to the axes morphology take form with strongly developed axes of the dendrites of the second order in the plane of the radial gradient. The graph-analytic method for assessment of these relations allows to predict, the area where the height of the ingot may appear dendrites with developed axes of the second order.
