AN ANOMALOUS INTERNAL FRICTION PEAK IN Au3Cu
K. IwasakiThe Institute of Physical and Chemical Research, Wakoshi, Saitama, 351, Japan
Abstract
An anomalous internal friction peak is observed prominently when the specimens are quenched from 1073°K and subsequently deformed below room temperature. This peak is anomalous in the following points. 1) At the peak temperature the period of vibration reveals a step of opposite direction to that associated with the usual relaxation peak. 2) The peak temperature varies very widely. 3) The peak is very sharp. The peak is tentatively interpreted to be due to some kind of order-disorder transition which may occur locally under the influence of dislocation motion.
