In order to find a generalized entropy production for steady‐state eutectic growth the entropy production per unit time and volume is to be determined. A relationship which expresses the entropy production per unit time and volume as a function of K RUPKOWSKI 's equations is shown. It is in a qualitative accuracy with L ESOULT ‐T URPIN 's theory. The above quantity is to be integrated over a distinguished volume of the unidirectionally solidified eutectic structure. A correlation between this volume and entropy production is discussed.
