Baseline Method for Determining the Solid Fraction

Abstract

A baseline method to determine directly the solid fraction using the cooling curve was proposed for solidification of undercooled melts. To construct the baselines, a sudden function ξα(x) is introduced. In terms of present method, the solid fractions during solidification of Zr metal and Al-7wt.%Si alloy were predicted. The predictions coincide with the results of the available methods.
