Effect of Ultrasonic Treatment on Microstructure and Mechanical Property of In Situ Al/2TiB Particulate Composites

Abstract:

Al/2TiB₂ in-situ composite was fabricated using salt-melt reaction method. Subsequently, it was re-melted and treated with high intensity ultrasonic waves for various time intervals. Substantial reduction in TiB₂ particle size down to ~ 300 nm along with significant improvement in dispersion is achieved with the aid of ultrasonic treatment. Ultrasonic treatment has resulted significant increase in hardness of Al/2TiB₂ in-situ composite.
