ÎÒÊǰÑCu·ÛºÍSi3N4·Û·ÅÔÚ¸ßÄÜÇòÄ¥»úÖнøÐÐÇòÄ¥µÄ£¬¶ÔͼÖеĽâÊÍΪ Figure 2 depicts the XRD patterns of as-milled Cu-25 wt% Si3N4 at different stages of milling. It was confirmed that only two phases of Cu and Si3N4 were present in the as-milled powders. It was also found that with increasing the milling time, the diffraction peaks of Cu and Si3N4 became broader. This change revealed a reduced grain size and an elevated strain energy stored inside particles, because of the severe plastic deformation introduced during ball milling. As the milling time increased, the diffraction peaks of the as-milled powders were rougher, suggesting that the deformation of the crystals became much stronger. ͼÖÐ(a)3 h, (b) 7 h, (c) 9 h, and (d) 12 h¡£ Éó¸åÈËÌá³ö What is the meaning of "rougher" XRD peaks?
