Abstract
In the present study, elemental mixtures of Al, Ni and Nd powders with nominal compositions of Al88Ni10Nd2 was mechanically alloyed for times up 110 h yields amorphous or nanocrystalline products. Structural changes and thermal behaviour of the mechanically alloyed powders at different stages of milling have been characterized by X-ray diffraction (XRD), differential scanning calorimetry (DSC) and scanning electron microscopy (SEM). The XRD, DSC and SEM results showed that solid state reaction occurred during mechanical alloying and nano-intermetallic compounds of the Al88Ni10Nd2 powders can be obtained. Microstructure of the mechanically alloyed Al88Ni10Nd2 powder indicates the formation of fine nanoparticles with a size of about 10-20 nm. However, no amorphous phase has been obtained in Al88Ni10Nd2 powders after milled for times up 110 h.
