Численное моделирование затвердевания сплавов при интенсивном сопряженном теплообмене
The paper considers the problem of determining the rate of cooling of metal during solidification at the intersection of the liquidus temperature under intense heat sink from the surface. The solution to this problem it is necessary to determine the process conditions, the boundary and initial conditions for which it is possible to get new alloys with microcrystalline structures. The article contains the necessary finite-difference equations , we have described the algorithm of the model and using the known experimental data, the model was tested. Using the model, it was investigated the effect of the size of the casting and the heat transfer coefficient on the cooling rate of the aluminum-based alloy at the liquidus temperature.
