摘要	The variable regularity of particle size, grain size and micro-strain of intermetallic compound MoSi2 powders with the increase of milling time during wet-milling were investigated by the means of laser granulometry, X-ray diffraction, scanning electronic microscopy. Microstructure features and refining mechanism of MoSi2 powder during wet milling were also discussed. The results show refinement mainly occurs in the early milling stage and then becomes stable after 40h milling. The crystal type of MoSi2 don't change after wet milling for 100 h. Superfine MoSi2 powder with average grain size of 14.2 nm and average particle size of 0.140 μm is obtained by wet milling method and distribution plot for particle size presents bimetal character of sub-micro zone and nanometer zone. The grain size and micro-strain exhibits relationship of Ε = 17.0844 D-0.4468. Refinement of particles mainly depends on grinding medium entering microcracks to accelerate crush of powder in the early stage of milling. Grinding medium coats particles to prevent them from agglomerating in after stage.
