Ball milling metallurgy

Apr 17, 2020

Jun 14, 2021 The vibratory ball mill is an excellent means of producing solid-state alloyed and dispersion-strengthened metals in amounts up to 4.5 kg (10 lb) or more, depending on the apparent density of the powder. Figure 21 (a) and 21 (b) show the microstructure of an aluminum-iron-cerium alloy and a transmission electron micrograph of oxide dispersion
