Nanocrystallization of Al88Ni10Nd2 Alloy by Mechanical Alloying

In the present study, mixtures of Al, Ni and Nd elemental powders with compound percentage ofAl88Ni10Nd2 were alloyed by mechanical alloying system for times up 110 h yieldsnanocrystalline products. The mechanically alloyed powders' structural changes and thermalbehaviour of different stages of milling were characterized by X-ray diffraction (XRD),differential scanning calorimetry (DSC) and scanning electron microscopy (SEM). The SEM,XRD and DSC results demonstrated that solid state reaction occurred during mechanical alloyingand nano-intermetallic compounds of the Al88Ni10Nd2 powders could be obtained.Microstructures of the Al88Ni10Nd2 mechanically alloyed powders were determined to show theformation of fine nanoparticles having a size of touching 10-20 nm. However, no amorphousphase was obtained in Al88Ni10Nd2 powders after milled for times up 110 h.
