摘要：

Evolution of phases during high-energy ball-milling of elemental powders of Nb and Si of composition Nb-16 at.% Si were studied as a function of milling time and milling power. Powders obtained were characterized by X-ray diffraction and calorimetry. Milling can result either in Nb-Si supersaturated solid solution or in a very fine partially amorphized mixture. Further milling of the amorphous mixture can result in mechanical crystallization and transformation that leads to formation of Nb, and Nb5Si3 and Nb3Si intermetallic compounds.
