文摘
- •
Ultrasonic treatment (UT) of Al–4.4Cu/2TiB2 composite has generated nano size TiB2 particles.
- •
Particle dissolution and re-precipitation is proposed as reason for nano TiB2 particle formation.
- •
Increase of ultrasonic power input and treatment time has increased reduction in TiB2 particle size.
- •
Yield strength of Al–4.4Cu/2TiB2 composite after UT is ∼2 fold higher than Al–4.4Cu alloy.
