Pores are common defects in the process of directed laser deposition (DLD) which not only greatly reduce the fracture toughness of ceramic materials, but also lead to the failure of shaped parts. In this paper, the formation mechanism of pores was an

Carbon fiber (C fiber) toughening nanoscale Al2O3-ZrO2 eutectic was prepared by ultrasonic-assisted directed laser deposition (DLD). The eutectic spacing detected by TEM was 50 ± 5 nm, which was 5–30% of the Al2O3-ZrO2 eutectic. The reasons for th
