摘要: Comparison of the formation enthalpy amorphous phase (ΔHam) to simple solid solutions (ΔHss) shows that diffusionless polymorphic crystallization occurs at low temperatures if ΔHam >ΔHss. In composition range where < ΔHss, via diffusion and temperature is roughly proportional holes size larger constituent. This model supported by data from literature 74 binary alloys. Formation enthalpies are calculated using Miedema's macroscopic atom approach. To calculate alloy should not be regarded as a random alloy, but certain degree chemical short-range order accounted for.
