The alumina, titania and graphite powder were milled in a ...
Recent researches on ball-milling of chitosan are mainly focused on the optimization of process parameters to obtain finer powders, neglecting the changes of physicochemical and structural properties during the milling process. The aim of this study, therefore, was to investigate the effect of the ball-milling treatment on properties of ...
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 …
