A Stability Function for Explicit Evaluation of the Mullins-Sekerka Interface Stability Criterion

Abstract

A stability function 𝒮 for explicit evaluation of the Mullins-Sekerka interface stability criterion is introduced and tabulated. Their criterion is then written in terms of 𝒮 and compared with the constitutional supercooling criterion for interface stability. From these results, experimental data can be analyzed and a conclusive test of the stability theory can be made.
