High-energy ball milling to enhance the reactivity of

In summary we have proved that high-energy ball milling is an effective technique to synthesize reactive Al-NPs. The introduction of air during milling enables to obtain powders with high specific areas: the continuous regeneration of the alumina layer maintains the hardness of the powders which in turn can be more easily broken.

Phase transformation of NiTi shape memory alloy powders

5/27/2009· Ball milling is effective in reducing NiTi alloy wire cuts into fine powders. The powders are partially amorphous. Prolonged milling causes contamination of O, Fe and Cr in the alloy powder. (2) The powder milled for short time (1 h) crystallized in a single-stage exothermic event. The activation energy of crystallization is 307 ± 12 kJ/mol. (3)
