Mixed 50Ni–50Ti powders were milled in an attritor high energy ball mill and the structural evolution of the milled powders characterised by X-ray diffraction analysis. The microstrain, crystallite size, and lattice parameters of the nickel and titanium crystals were measured. The results show that increases in the rotational velocity and the total ball volume/tank volume ratio leads to a decrease in the crystallite size and rapid changes in the microstrain and lattice parameters, which enhance the amorphisation rate, thereby reducing the time required to obtain afully amorphous phase.MST/2079
