Abstract:Nano-scale Al2O3-ZrO2 eutectic ceramic structures with shapes of thin-wall and cylinder were prepared by ultrasonic-assisted laser engineered net shaping. In the preparation process, the power of ultrasonic was adjusted in real-time on the molten pool. The generation of refining grain by ultrasonic were discussed based on the principle of crystallography. Two methods to improve the fracture toughness were analyzed. The average eutectic spacing was 60-70 nm, and the fracture toughness was 7.67 MPa.m(1/2). (C) 2017 Elsevier By. All rights reserved.
