Abstract
A deformation calorimeter that serves to deform a sample material whose temperature changes as a function of the deformation. The temperature change causes heat to flow into the material or out, depending on the character of the deformation, to cause a pressure change in a gas in and around the material. An analyzing scheme is employed to relate the pressure change to the amount of heat evolved during sample deformation.
