采用X射线衍射和透射电镜研究了高能球磨法制备的WC-10%Co纳米复合材料的微观结构。在研磨之后，WC相被细化至11 nm的晶粒尺寸。WC中位错密度高，造成严重的晶格畸变。在某些区域发现了Burgers矢量为1/3[1（2）/1 0]的位错。(C)2003由Elsevier Ltd.代表Acta Materialia Inc.出版。
The microstructure of WC-10%Co nanocomposite prepared by high energy ball milling was investigated by X-ray diffraction and transmission electron microscopy. The WC phase was refined to a grain size of 11 nm after milling. The dislocation density in WC was high and caused severe lattice distortion. Dislocations with Burgers vector 1/3[1 (2) over bar 1 0] were identified in some areas. (C) 2003 Published by Elsevier Ltd. on behalf of Acta Materialia Inc.
