    The ball-milled samples were then extracted twice with dioxane-water solution (96 vol/vol) in a shaker at 190 rpm for 24 h at 27°C in the dark. The extractions were performed by using 10 ml of solvent per g of ball-milled wood. The dioxane-water extracts were combined and the solvents were removed at 35°C under reduced pressure.

  • Characterization of high-energy milled alumina powders

    The precursor ceramic powder used in this study was a Alcoa A1000 alumina. The high-energy milling processing of the dry powder was performed in a high-energy vibratory ball mill (Spex 8000 mixer/mill) using hardened steel vials and balls as milling media in air. The use of alumina as milling media was discontinued due its high rate of wear.

    Processing and Microstructural Characterization of a Ti-Cr-Nb Alloy Synthesized by High-Energy Ball-Milling increase on Fe contamination can be explained by the fast formation of the BCC solid solution observed on the XRD patterns. This BCC phase is very hard when compared to the pure metallic elements thus leading
