采用ZJM10T型搅拌球磨机和X射线衍射仪(XRD),研究了机械研磨(MG)条件下MoSi2的同素异构转变及其非晶化,并对其转变机理进行了初步分析和讨论.结果表明,当球料比为10∶1,球磨机转速为450r/min时,MoSi2粉末在机械球磨80h后,没有H MoSi2生成;而当球料比为20∶1,转速为600r/min时,机械球磨60h,已有少量的H MoSi2生成,同时随着球磨时间的增加H MoSi2的量逐渐增加.继续机械研磨,MoSi2合金粉末呈非晶化.试验结果证实相对高的能量有助于MoSi2的固态相变.
The allometric transformation and amorphization of MoSi2 under mechanical milling (MG) conditions were studied by using ZJM10T agitating ball mill and X-ray diffraction (XRD), and the transformation mechanism of MoSi2 was analyzed and discussed. , When the ball material ratio is 10: 1, the speed of the ball mill is 450r / min, the MoSi2 powder has no H MoSi2 after mechanical milling for 80h; and when the ball material ratio is 20: 1 and the rotating speed is 600r / min, 60h, a small amount of H MoSi2 has been formed, and the amount of H MoSi2 increases with the milling time.After mechanical milling, the MoSi2 alloy powder is amorphized.The results show that the relatively high energy contributes to the solid phase of MoSi2 change.
