Efficiency of high energy over conventional milling of granulated blast
During high energy milling, severe plastic deformation process of the powder particles takes place stimulated by ball-particle-ball and ball–particle vial wall interactions [39], [40]. These results compare fairly with the general trend of amorphisation reported by Kriskova et al. [29] on slag bead milling for 6 h.
