03.02.2012· The temperature during milling can depend on the kinetic energy of the ball and the material characteristics of the powder and milling media. The temperature of the powder influences the diffusivity and defect concentration in the powder influencing the phase transformations induced by milling[7]. Higher temperatures are expected to result in phases which need higher atomic mobility
