Conclusions 1.The damping capacity and the structure of the ß-alloys of the Cu-Al-Zn system after quenching in air are determined by the general degree of alloying expressed by the electron concentration and by the ratio of the alloying elements.2.The alloys with the electron concentration e/a<1.45–1.48 show diffusion breakdown and the level of damping capacity increases with the increase of electron concentration as a result of the increase of the amount of martensite in the structure.3.In the alloys with the electron concentration e/a>1.45–1.48 the damping capacity is determined by the ratio of the two types of martensite present in the structure, 2H and M18R. The amount of M18R martensite increases with the increase of the zinc content and reduces the damping capacity and, conversely, the increase of the aluminum content increases the amount of 2H martensite and also increases the damping capacity. |
