چکیده انگلیسی
To prepare metal flakes with a high flaking level and investigate the microstructure of metal flakes, nickel and copper powder were mechanically milled in liquid environment and the microstructure of powders was investigated by X-ray diffraction. The milling process can be divided into flaking and broken stages. At the flaking stage, milled metal powders exhibited high flaking level and flaky microshape, and ã2Â 0Â 0ã became preferred orientation. While at the broken stage, the milled powders presented a low flaking level and irregular microshape, and ã2Â 0Â 0ã was not preferred orientation any longer. The grain size, microstrain and dislocation density along ã2Â 0Â 0ã direction varied with milling time differently from that along ã1Â 1Â 1ã direction. The flaking level of the milled powders was related to the ã2Â 0Â 0ã preferred orientation, and more closely to the deformation mechanism. We can strengthen the formation of ã2Â 0Â 0ã preferred orientation to obtain metal powders with a high flaking level.
