Effect of high intensity ultrasound on Al3Ni2, Al3Ni crystallite size in binary AlNi (50Â wt% of Ni) alloy

Crystallite size of the intermetallics is one of the most important parameters that can influence kinetics of catalytic reactions. Analysis of the crystallite sizes of Al3Ni and Al3Ni2 intermetallic phases using Scherrer and Williamson-Hall methods reveals that the sonomechanical impact of ultrasound on suspensions of AlNi particles in ethanol results in crystallites growth and microstrain reduction.
