The evolution of amorphous and nanocrystalline phases in mechanically alloyed Mg1.9M0.1Ni (M=Ti,Zr,V) was studied under different milling conditions by differential scanning calorimetry (DSC) and X-ray diffraction (XRD) analysis. It was found that the presence of air (oxygen and nitrogen) accelerates the nanocrystallization reaction, but has no influence on the amorphous phase formation during ball milling. The mechanochemical work necessary to obtain a certain degree of amorphization or nanocrystallization in the Mg2Ni-based alloys was determined and it was found to control the end product of milling. © 2004 Elsevier B.V.
