Description

Four ordered alloys Fe-38.5, 40.55, 44 and 47 at.% Al were irradiated with neutrons at liquid hydrogen temperature. Four recovery stages are found at the approximate temperatures of 100 K, 200 K, 500 K and 620 K. Their relative amounts are not influenced by the alloy composition but it is observed that the two latter stages are shifted to higher temperatures when the aluminium concentration increases. The activation energies and the dose dependence are investigated. In all the cases, the stage at 500 K is the most important one and its behaviour is in agreement with the free migration of interstitials while close pair recombination occurs near 100 K. (author)

Abstract (French)

Quatre alliages Fe-38,5-40,55-44 et 47at. % Al ordonnes ont ete irradies aux neutrons a la temperature de l'hydrogene liquide. Quatre stades ont ete mis en evidence vers des temperatures approximatives de 100 K, 200 K, 500 K et 620 K. Leurs amplitudes relatives ne sont pas influencees par la composition de l'alliage; par contre, les deux derniers stades se deplacent nettement vers les hautes temperatures lorsque la concentration en Al augmente. On a precise les energies d'activation ainsi que l'influence de la dose d'irradiation. Dans tous les cas, le stade situe vers 500 K est le plus important et presente les caracteristiques de la migration libre des interstitiels alors que les paires proches se recombinent vers 100 K. Four ordered alloys Fe-38.5-40.55-44 and 47 at.% Al were irradiated with neutrons at liquid hydrogen temperature. Four recovery stages are found at the approximative temperatures of 100 K, 200 K, 500 K and 620 K. Their relative amount are not influenced by the alloy composition ...
