Fe-Al alloys containing 25 and 31.5 at. % Al have been studied by internal friction, X-ray diffraction and dilatometric analyses. These techniques show for the first time that two internal friction peaks appear during the change in long range order type which occurs during the precipitation at 300degreesC of the metastable phase B2(FeAl). These pea...

The aim of the present work is to study order-disorder transformation in some alloys of the Fe-Al system (with 9.8, 21.5 and 25 at.% Al). The synthesis and the analysis of numerous and interesting results obtained by dilatometric and calorimetric analysis have allowed us to assert that the ordering reaction is a rapid process and that long ageing a...
La précipitation discontinue attire toujours l'attention des chercheurs, car divers mécanismes la contrôlent. Beaucoup de travaux ont été consacrés à l'étude du mécanisme de la précipitation et de la dissolution, aux différentes réactions discontinues, à l'influence des traitements thermo-mécaniques et à l'addition d'un troisième élément dans le bu...
Les phénomènes de restauration des propriétés d'équilibre thermodynamique au cours de la décomposition des solutions solides sursaturées et la recristallisation des matériaux écrouis, sont en principe influencés par la présence des impuretés. La précipitation discontinue des alliages binaires à base de cuivre (Cu-9% Sb et Cu-15% In) se produit géné...
