โฆ Synopsis
The results of the calorimetric determination of the stored energy for polycrystalline copper deformed in tension at room temperature are reported. They are found to be in good agreement with those of Williams obtained for similar specimens and test conditions. Differences between the new stored energy data and those of other authors can be rationalized in terms of calorimetric technique.
ENERGIE STOCKEE DANS LE CUIVRE POLYCRISTALLIN DEFORME A TEMPERATURE AMBIANTE
Les auteurs presentent les resultats de la determinltion calorimetrique de l'energie stockee pour le cuivre polycristallin deform6 en traction I temperature ambiante. Ces resultats sont en bon accord avec ceux de Williams obtenus pour des Bchantillons et des conditions d'essais analogues. Les differences existant entre les nouveaux resultats d'energie stock&e et deux obtenus par d'autres auteurs peuvent &tre expliques rationnellement par la technique calorimetrique utilisee.

Sie sind in guter tfbereinstimmung mit Resultaten van Williams an ahnlichen Proben und unter ahnlichen Versuchsbedingungen. Unterschiede zwisohen diesen neuen Daten iiber gespeicherte Energie und den Ergebnissen anderer Autoren konnen mit Hilfe der kalorimetrischen Methode verstanden werden.
