The columnar-to-equiaxed transition in the solidification of a Ti–10V–2Fe–3Al alloy is considered during vacuum arc remelting. A GV curve is plotted using a linear model of a multicomponent alloy along with modified Hunt (to determine temperature gradient G as a function of supercooling ΔT) and Ivantsov (to determine the concentrations at the dendrite tip versus liquidus isotherm velocity V) models. The unknown parameters of the models are determined by comparing the results of model calculations with experimental data, which are also obtained in this work. The plotted GV curve is compared with the GV curve of a VT3-1 alloy.
