Abstract
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.
