: The Effect of Milling Time and Speed on Solid Solubility ...

2021-3-24 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.
