• The change of internal friction accompanied by the recovery of cold-work in aluminium was measured and compared with those in other physical properties, namely, hardness and thermoelectric power. The results showed that (1) internal friction increases monotonously with cold-work ; (2) the values of internal friction and other properties decrease exponentially by annealing, the relaxation times and saturation values being functions of annealing temperatures ; (3) the internal friction changes remarkably by low temperature annealing, while other physical properties do not change. These results were explained from the concept that the internal friction is caused by the viscous behaviors of grain boundaries which consist of various kinds of lattice defects.
