Аннотация
The production of steel and alloys ends with the casting of metal in a mold. In casting an alloy, its liquidus temperature must be known. This is especially important in developing a smelting technology for nickel alloys with a large number of alloying elements. In the present work, a model is developed for predicting the liquidus temperature of complex nickel alloys. The regression coefficients of the equations describing the liquidus and solidus lines of binary systems are determined on the basis of literature data regarding the phase diagrams of binary nickel systems with different elements. With increase in the set of data regarding the regression coefficients from 21 to 27 elements, a broad spectrum of complex nickel alloys may be covered. When the model based on data for binary alloys is tested for experimental liquidus temperatures of complex nickel alloys, the conclusion is that the model permits the prediction of the liquidus temperature of such alloys with sufficient precision for practical purposes (±19.8°C).
