摘要

Synthesis of the Nb-Si in-situ composite was attempted by mechanical alloying of element powders in vario-planetary ball mill. The particles size distribution was measured by laser diffraction, microstructures were examined with scanning electronic microscope, and the phase constituent were analyzed by X-ray diffraction. The amorphization of the Si during mechanical alloying, large amount of deformation of Nb crystal structure, and after all - the formation of supersaturated solid solution of Nb was observed. To stabilize microstructure and phase composition, a spark plasma sintering was attempted. After SPS microstructure consist of three main phases - Nb_(ss), Nb_5Si_3 and Nb_3Si.
