Abstract

A dilatometer is described in which the length changes of a thin wire are transmitted to a capacitive detector by a see-saw suspended on a phosphor-bronze leaf. The high-temperature anelastic deformations were determined by measuring the frozen-in length change after various annealing steps at a given low temperature. The samples were annealed within the dilatometer by self-resistance heating. It was found that the accuracy of the length determination is limited by the stability of the temperature distribution in the sample and in the dilatometer frame.
