Abstract

A method is described for estimating the velocities of the solidification front from the cooling rates immediately after solidification which can easily be determined from cooling curves by means of thermocouples. The equations have been tested by means of experiments carried out with a eutectic aluminium–silicon alloy and satisfactory agreement has been obtained. Possible practical applications are non-destructive determination of local microstructural parameters and, in turn, local properties, or local cooling conditions from simple counting measurements from metallographic samples.
