本文研究了急冷Al-8.3at%Si-8.5at%Ge合金的微观结构及正常-超导转变特性,结构分析表明,样品中存在晶态及非晶态两种不同的区域,经100℃/50hr热处理后,电阻-温度及电阻-磁场转变曲线上均出现明显的台阶。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.
