Abstract
Metallic glass samples with compositions Zr 65Al 7.5Cu 27.5 and Pd 77Cu 6Si 17, for which loss factors of up to 10 -2 have been reported, are reinvestigated with an electrostatic vibrating cantilever technique that detects dissipation factors tan δ as low as 10 -4. It is found that tan δ ≈ 4×10 -4 is a typical value for these alloys well below T g, suggesting that previous results were limited by instrumental resolution. While aging the glasses increases their elastic moduli considerably, the measured loss factor is affected only marginally by thermal history.
