Its crystallization processes induced by mechanical milling (MM) and annealing under normal and high pressure were studied. The crystallization product of the amorphous Fe-N alloy induced by MM and annealing at temperatures between 690 and 800 K under pressures of 3-4 GPa is ε-FexN, while the thermal crystallization product under normal pressure is γ′-Fe4N. The difference between the crystallization products produced by mechanical and thermal crystallization is attributed to the effects of local pressure and local temperature produced by ball collisions.||Source Title:||Journal of Physics Condensed Matter||URI:||http://scholarbank.nus.edu.sg/handle/10635/98255||ISSN:||09538984||DOI:||10.1088/0953-8984/14/44/444|
