✦ Synopsis

friction peak has been found in iron at about lOOoK, and possibly in molybdenum at about 300°K. These internal friction peaks occur at temperatures corresponding to the ductile to brittle transition of these materials in slow tension tests. The possible role of hydrogen in causing the 100°K peak in iron is briefly discussed. LE FROTTEMENT INTERNE DU FER ET DU MOLYBDENE AUX B.ASSES TEMPERATURES Une bosse a ett? trouvee aux courbes de frottement interne du fer aux environs de 100°K et probablement du molybdbne aux environs de 300°K. Ces bosses se presentent aux temperatures correspondant B la transition de 1'Ctat ductile a l'etat fragile de ces materiaux dans des essais lents d'extension. Le rBle possible de l'hydrogene dans la production de cette bosse a lOOoK dans le fer est brie-ement discutee. I *July 21, 1953.
