An amorphous Ni 1-x Mo x phase has been observed after milling and no intermetallic intermediate phase involved in the amorphization process. The mechanism of the amorphization has been discussed, an amorphous Ni 1-x Mo x forms accompanying with the Mo diffusing into Ni matrix. Meanwhile, the limitation of the classification of the three amorphization reactions types of MA has also been pointed out. 机械合金化 中子衍射 非晶化 合金玻璃 mechanical alloying neutron diffraction amorphization metal glass O751 1993-02-01 2021-04-01 2
