“…There are several available methods, which have been developed in the past, that can be adopted to solidify alumina-based nanoeutectic ceramics in the laboratory, such as laserheated float zoning (LFZ) [8,13,14,26,[28][29][30]32,[34][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49][50][51][52][53], micro-pulling-down (µ-PD) [23,54], aero-acoustic levitators [55], high-energy density beam (HEDB) (laser or oxy-acetylene flame) surface (zone) (re)melting [24,33,[56][57][58][59][60][61][62][63][64][65][66][67][68], plasma spraying [69,70], directed energy deposition (DED)…”

Nanocrystalline alumina-zirconia-based eutectic ceramics fabricated with high-energy beams and composed of ultrafine, three-dimensionally entangled, single-crystal domains are a special category of eutectic oxides that exhibit exceptionally high-temperature mechanical properties, such as strength and toughness as well as creep resistance. This paper aims to provide a comprehensive review on the basic principles, advanced solidification processes, microstructure and mechanical properties of alumina-zirconia-based eutectic ceramics, with particular attention to the status of the art on a nanocrystalline scale. Some basic principles of coupled eutectic growth are first introduced based on previously reported models, followed by concise introduction of solidification techniques and the control strategy of solidification behavior from the processing variables. Then, the microstructural formation of nanoeutectic structure is elucidated with regard to different hierarchical scales, and mechanical properties such as hardness, flexural and tensile strength, fracture toughness and wear resistance are discussed in detail for a comparative study. Nanocrystalline alumina-zirconia-based eutectic ceramics with unique microstructural and compositional characteristics have been produced with high-energy beam-based processes, and in many cases, promising improvements in mechanical performance have been reported as contrasting with conventional eutectic ceramics.

“…[39][40][41][42] It has been shown that depending on the eutectic composition, the solidi-cation process and the growth parameters, the resulting microstructure consists of two phases (YAG, Zr(Y)O 2 ) distributed in sapphire (Al 2 O 3 ) matrix. The experimental works carried out 17,[43][44][45][46][47][48][49][50] for eutectic compositions highlight the inuence of solidication parameters: growth rate, chemical composition and thermal gradient. Depending on the pulling rate conditions, the microstructure will also undergo transitions linked to the destabilization of the interface.…”
