Summary
The paper describes the stress relaxation phenomena in AM50 magnesium alloy and Mg reinforced by short Saffil fibres. The materials were prepared by squeeze casting. The specimens were annealed step by step at increasing temperatures and then stress relaxation was measured at temperature of 31°C. The stress relaxation curves were analysed and the modulus defect, relaxation strength and activation energy were estimated. It is very difficult to draw conclusions on the mechanisms responsible for the stress relaxation but a part of the relaxation strength is due to reversible dislocation movement.
