It has been found that a mechanically induced self-propagating reaction (MSR) occurs within 2 hours of milling and it produces very fine polycrystalline powder having a hexagonal Fe2P structure. Further milling up to 24 hours did not change the crystalline and average particle sizes or the phase composition of the milling product. When x is 0.65, no reaction among the reactants has been observed even after 24 hours of milling. As the P content decreases in MnFeP1-xAsx, the incubation time for the MSR has increased and the lattice constants in both a and c axes have changed. 한국분말야금학회 고에너지볼밀링을 이용한 MnFeP1-xAsx 나노분말의 합성 Synthesis of MnFeP1-xAsx Nanocrystalline Powders by High-Energy Ball Milling Article 2 한국분말야금학회지, v.10, no.2, pp.129 - 135 한국분말야금학회지 10 2 129 135 kci ART000994481 Mechanochemical processing High energy ball milling Nanocrystalline powder Transition metal pnictide Mechanochemical processing High energy ball milling Nanocrystalline powder Transition metal pnictide
