The microstructure and superconducting-normal transitions of fast quenched supersaturated solid solution Al-lat% Ge alloy have been studied. X-ray structural analysis of the sample indicated that Al-lat% Ge alloy consists of a homogeneous supersaturated α-Al(Ge) solid solution.The resistance measurement shows that for solid solution alloy α-Al(Ge) Tc≈1.44K, which is higher than that of pure Al.
