【Abstract】 On the basis of the regular patterns of the structural transitions or the metal-metalloid amorphous alloys under high pressure, the A15 Nb3Si with highest superconducting transition temperature of 19.1 K has been synthesized under lower pressure by the phases decomposition processes. It was estimated that the compositions of A15 phase are near stoichiometric from their lattice parameters. ;更多还原
