“…The columnar structure of the ingot is formed at certain speeds. This is due to the different values of the temperature gradient arising at the boundary between the liquid and solid phases [7]. As was mentioned above [8], the following factors affect the value of the temperature gradients of a liquid-solid phase: thermophysical properties of the material; rate of crystallization; latent heat of crystallization; thermal convection that develops during melting.…”
