Effect of thermophysical conditions of solidification on the structure of cast metal

Conclusions

  1. 1.

    The dispersity of the dendritic structure depends on the solidification rate, temperature gradient in the liquid phase, and the nature of the alloy.

  2. 2.

    An increase in the density of the dendritic structure by a factor of two to three is due to the refining of nonmetallic inclusions and their more even distribution, which improves the ductility of the cast and rolled metal by 15–20%.
