The amplitude-independent mechanical quality factor Q of grade 1 commercially pure polycrystalline titanium has been measured in the temperature range from 50 mK to 300 K. Data were obtained from a torsional mode of a mechanical resonator at about 1 kHz. Maximum Qs of 2ยฑ3 million were observed below

Quality factors of miniaturized 50โ coplanar resonators with an inner conductor width of 52 m and with sputtered niobium on low loss substrates in the order of 20,000 are achieved at 1.8 GHz and 4.2 K. They are investigated in dependence of the shapes of the stripe edges and of slots and stems in th
The amplitude-independent quality factors (Qs) of polycrystalline aluminium of 99.999 wt% purity, and the commercial aluminium alloys 2024, 6061 and 7075 have been measured in the temperature range 50 mK-300 K. Data were obtained at about 1 kHz from a torsional mode of machined monolithic mechanical
