β¦ Synopsis
This paper reports a study of grain boundary segregation of antimony and nickel in iron. These results show that nickel additions to the matrix increase antimony segregation. This observation is in agreement with previously reported work. Antimony additions to the matrix or segregation to the grain boundary have no measurable effect on nickel segregation. Decarburization increases segregation of both antimony and nickel.
R&um&Cet article rapporte une itude de la stgrbgation intergranulaire de l'antimoine et du nickel dans le fer. Ces rtsultats montrent que des additions de nickel a la matrice accroissent la s&gr&gation de I'antimoine. Cette observation est en bon accord avec un travail pr&sent& anterieruement. Dans le cas de l'antimoine, son addition B la matrice ou sa stgrkgation aux joints de grains n'ont pas d'effet mesurable sur la segrlgation du Nickel. La decarburation accroit la stgrigation de I'antimoine et du nickel.

Korngrenzensegregation in Eisen zeigen, daD Zugaben von Nickel zur Matrix die Segregation von Antimon verstgrken. Diese Beobachtung stimmt mit friiher vorgelegten Arbeiten iiberein. Die Antimonsegregation an die Korngrenze oder Zugaben von Antimon zur Matrix beeinflussen die Nickelsegregation im Rahmen der MeDgenauigkeit nicht. Entkohlung verstarkt die Segregation sowohl von Nickel als such Antimon.

From the viewpoint of existence of linear dependence between entropy and enthalpy of grain boundary segregation, the meaning of the entropy term is discussed. It is suggested that negative values of segregation entropy for silicon segregation at individual grain boundaries in a-iron reΓect an "order
