    Abstract

    Mechanical alloying of Al-Ti was performed by high-energy ball milling at ambient temperature under argon atmosphere. A Fritsch Pulverisette-5 planetary type ball mill was used for the mechanical alloying for 2 up to 30 hours with the ball milling size of 15 mm and the rotational speed of about 360 rpm. The balls-to-powder ratio was 20: 1 (in weight percent). The final products have been characterized by SEM and XRD. The SEM results showed that the average particle size of mechanically alloyed Al-Ti powders decreased with increasing milling time and the particle size was smaller than 1.63 μm after 30 hours milling. The XRD results showed that the crystallite size of mechanically alloyed Al-Ti powders decreased with increasing milling time and the steady-state crystallite size was approximately 17.6 nm. It also found that the peaks of Ti begin disappear with the increasing of milling time, which indicates the forming alloying of Ti atoms in the Al matrix. The SEM results confirmed that the nanocrystalline produced were binary alloy of Al-Ti and no other impurities detected in the particles. The optimum milling time for the mechanical alloying of nanocrystalline Al-Ti was 30 hours.
