The effect of milling temperature on the amorphization of mechanically alloyed Cu 30 Ta 70 has been investigated in 1991 by Lee et al. [45] In their experiments, they ballmilled the elemental powders of Cu 30 Ta 70 at two different controlled temperatures of 37°C and 200°C for 100 h under the same milling conditions. They realized that ball milling at 200°C leads to the formation of an ...
