摘要: Models for computer simulation of solidification alloys in two different geometries have been developed. These models allow us to study the roles crystal nucleation and heat transfer effects modes growth on evolution microstructure during solidification. In particular, by applying powerful versatile tool comprised solute-drag model thermodynamic modeling alloy system, we are able predict formation a consisting alternating layers parallel front. This type banded microstructure, experimentally observed Al-Cu, Al-Fe, Ag-Cu alloys, has not satisfactorily explained before.
