Multivariable control of ball-milled reactive material composition and
Ball milling energy is fundamentally affected by two variables: (i) process and (ii) powder variables, whereas; heat capacity, powder density, and atomic mass are the main powder characteristics. On the other hand, the milling duration, the volume of milling vial, rotational rate, the ball to powder ratio are the process parameters [12–17].
