摘要:
利用高能棒磨机,对Mo-Cr二元不互溶体系进行机械合金化,通过改变棒料比、棒磨时间以及棒磨罐填充比例,探索形成Cr(Mo)固溶体的条件。研究发现,Mo:Cr=1:1(wt%)配比的粉末,在批料40 g,棒料比60:1,棒磨时间16 h棒磨条件下可获得完全固溶的Cr(Mo)超饱和固溶体;对获得的Cr(Mo)固溶体粉末进行物相、形貌以及热稳定性等分析,探索机械合金化棒磨条件下,二元不互溶Mo-Cr体系的固溶合金化过程。

Abstract:
With the method of high-energy rod mill, the Cr (Mo) solid solution was prepared and by changing the ratio of the material, the grinding time and the filling ratio of rod mill, the conditions for forming Cr (Mo) solid solution were explored. It shows that when the batch is 40g, bar ratio is 60:1, rod mill time is 16 h, with the powder of Mo:Cr=1:1 (wt%) ratio, we can get the completely soluble Cr (Mo)-saturated solid solution. And we also analyzed the phase, morphology and thermal stability of Cr (Mo) solid solution powders, and explored the process of the solid solution alloying of the immiscible Mo-Cr system with the condition of mechanical alloying.
