Abstract
The interactions between dislocations and point defects have been studied in magnesium containing 100 p.p.m. of impurity atoms. The experiments where conducted on one hand by measuring the ultrasonic attenuation changes due to a bias stress and on the other hand by measuring the internal friction on a torsion pendulum working at 2 Hz.
