ABSTRACT:
A torsion pendulum apparatus and a dialometer are combined for simultaneous measurement of the internal friction and the expansion of an alloy. The combination is controlled by a programmable controller so as to conduct in-situ measurements of the internal friction and the expansion of a metal during its phase transformation or specific heat treatment. The results of the internal friction measurement and the expansion measurement can be checked and assumed by one another so that more accurate and detailed information can be obtained for the study of metal alloys.
