Abstract
The adiabatic thermoelastic temperature change was determined as a function of temperature and stress in nickel and Armco iron. The results are in agreement with an equation first derived by Lord Kelvin. Near the Curie temperature the thermoelastic effect changes appreciably. Calculations confirm that the thermal expansion coefficient of iron decreases in the vicinity of the Curie temperature as predicted by the theory of ferromagnetism.
