A Deformation Calorimeter

Abstract

A calorimeter has been constructed which adiabatically deforms metals with a known mechanical energy. The energy which is stored in the sample as a result of the deformation is the difference between the supplied energy and the heat which is found by the increase in sample temperature. It is also possible to follow subsequent energy releases which take place immediately following the deformation; for some materials this release can be an appreciable fraction of the stored energy. The results for the stored energy are considered to be accurate to approximately 10%.
