Based on their results [42], it is concluded that the rate of amorphization depends strongly on the kinetic energy of the ball-mill charge and this depends on the number of opportunities for the powder particles to be reacted and interdiffused. Increasing the W b:W p ratio accelerates the rate of amorphization, which is explained by the increase in the kinetic energy of the ball-mill charge ...
