Mechanical Milling C
Phase, microstructure and mechanical properties evaluation ...
The phase transition, microstructure evaluation and mechanical properties of AlCoCrFeNi alloy during mechanical ball milling were studied. The results show that the content of FCC phase decreases gradually with increasing milling time to 20 h. The amorphous phase can be obtained completely when extending the milling time to 84 h.

Effect of Mechanical Milling and Cold Pressing on Co …
Mechanical milling suppresses an order–disorder phase transition in the investigated temperature range. Nevertheless, two main regimes can be identified, with two clearly distinct activation energies. Powder X-ray diffraction and 23 Na solid-state NMR reveal two different Na + environments, which are partially occupied, in the bcc polymorph.
