| Abstract: | The microstructure and superconducting-normal transitions of fast quenched Al-8.3 at%Si-8.5at%Ge have been studied. Structural analysis of the samples indicated that Al-Si-Ge alloy consists of two phases: an amorphous phase and a supersaturated α-Al (Si, Ge) solid solution. After heat treatment at 100℃ for 50 hr, a double superconducting transition can be observed in both their resistance-temperature and resistance-intensity of magnetic field characteristics. |
