Mechanical alloying of the Fe−Zr system. Correlation between input energy and end products
- 421 Downloads
Kinematic equations describing velocity and acceleration of a ball in a vial of a planetary ball-mill have been derived. The consequent energy transfer from the mill to the system constituted by the powder, the balls and the vials have been evaluated by theoretical-empirical approach. Mixtures of elemental iron and zirconium powders corresponding to the average Fe2Zr composition have been mechanically alloyed in different milling conditions. The end products strongly depend on the operative milling conditions and a clear correlation between them and the input energy has been found.
