Ball Milling and Annealing of Co-50 at% W Powders

2013-12-24 · Consequent annealing of unmilled compacts yielded metastable phases. Upon 10 and 20 h ball milling of Co-W powder, no alloying was obtained. Although milling did not yield significant crystal changes in W and Co ground state struc- tures, its effect is evident during subsequent annealing. An eta phase is obtained for the first time from ...
