Purpose: of this paper is to study the damping behaviour of ZC63 magnesium alloy and the same alloy reinforced with short Saffil fibres. Design/methodology/approach: Samples were thermally cycled between room temperature and increasing upper temperature of the thermal cycle and the logarithmic decrement were measured at room temperature. Findings: The strain amplitude dependence of the logarithmic decrement can be divided to two components: the amplitude independent and the amplitude dependent. While the thermal treatment does not change the amplitude independent component, the amplitude dependent part increases with increasing upper temperature of the thermal cycle. Research limitations/implications: Redistribution of solute atoms during thermal cycles is the reason for the observed changes in the amplitude dependence of decrement. Thermal stresses arise in the composite at the interfaces between the matrix and the reinforcement owing to a considerable mismatch of the thermal expansion coefficients of the matrix and that of the reinforcement. Practical implications: The ZC63/Saffil composites may be used as damping materials. Originality/value: New results on the damping behaviour of ZC63 alloy and its composite including internal friction were obtained.
