Abstract
Internal friction measurements have been carried out for a number of face-centred cubic CuNiZn alloys, especially the alloys around the composition Cu2NiZn. Damping measurements are carried out using an inverted Kê-type pendulum equipped with an optical detector. With an extrapolation in the ageing time relaxation data for the disordered structure were obtained. Also shear moduli and Young's moduli are reported on the same alloys.
