MATHEMATICAL MODELS OF CALCULATIONS OF PARAMETERS OF CRYSTALLIZATION OF BINARY ALLOYS BY MEANS OF COMPUTER THERMAL ANALYSIS
Mathematical models of crystallization of binary metal alloys crystallizing in the temperature range are proposed. These models are intended for use in the composition of quality control systems for cast alloys based on computer thermal analysis. The proposed models make it possible to calculate the time dependences of the relative amounts of the solid and liquid phases using the data of the cooling curve, as well as to determine the intensity of the increase of the amount of the solid phase. The method of determining the temperature dependences of the specific heat and latent crystallization heat using the data on the temperature-concentration dependences of the free energies of the phases forming the system under study was used.
