研究了球磨时间和球磨速度对V在Al中固溶度和晶粒细化的影响。采用高能球磨制备Al-xV（x= 2、5和10 at.%）合金在280和350 RPM的研磨速度下。球磨时间在10至100小时之间变化。在室温下，在3GPa的单轴压力下对球磨合金进行了固结。采用X射线衍射（XRD）分析方法，研究了Al-xV合金中V的固溶度和球磨后的晶粒尺寸。高能球磨使合金具有纳米晶结构和Al-V固溶体的形成。V在Al中的固溶度和晶粒细化程度取决于球磨速度、球磨时间和合金中V含量。
The effect of milling time and speed on solid solubility of V in Al and grain refinement was studied. High-energy ball milling was used to produce Al-xV (x= 2, 5, and 10 at.%) alloys at milling speeds of 280 and 350 RPM. The ball-milling time was varied from 10 to 100 hours. The ball-milled alloys were consolidated under uniaxial pressure of 3GPa at room temperature. The solid solubility of V and grain size after ball milling of Al-xV alloys were estimated using the x-ray diffraction (XRD) analysis. High-energy ball milling imparted the nanocrystalline structure and formation of Al-V solid solution. Grain refinement and solid solubility of V in Al were dependent on the milling speed, milling time, and V content in the alloy.
