Al-alloyed MgB2 was prepared by solid state reaction of Mg (1-x)A1(x) alloy and crystalline B powder particles. The nominal composition of the samples was Mg1-xAlxB2, with x = 0, 0.1, 0.2, and 0.3. Microstructure and chemical composition have been investigated by scanning electron microscopy (SEM), electron probe microanalysis (EPMA), and...
