Microstructure of Y2O3 doped Al2O3/ZrO2 eutectic fibers grown by the micro-pulling-down method

Microstructure Evolution and Model Analysis of Al2O3/ZrO2 Hypoeutectic Ceramic During Rapid Solidification

“…Al 2 O 3 -ZrO 2 eutectic ceramics have a good combination of physical, thermal and mechanical properties, such as ultra-high hardness, excellent oxidation resistance and strength retention at elevated temperatures [1][2][3] . These excellent properties make Al 2 O 3 -ZrO 2 eutectic ceramics potential for a wide range of applications.…”

“…These excellent properties make Al 2 O 3 -ZrO 2 eutectic ceramics potential for a wide range of applications. Generally, eutectic ceramics were mostly prepared by Bridgman method 3 , laser heated floating zone method 4,5 , micro pulling down method 6,7 , combustion synthesis method 8,9 , thermal explosion spraying [10][11][12] and so on. In addition, the mechanical properties of the Al 2 O 3 -ZrO 2 eutectic ceramics are mainly decided by microstructure which is influenced significantly by the cooling rate of the melt.…”

Tb3Sc2Al3O12-TbScO3 eutectic self-organized microstructure for metamaterials and photonic crystals application

“…The m-PD method was invented in Japan, originally for growth of single crystal fibres [23][24][25][26]. The growth of oxide-oxide eutectics for high strength materials has been already reported by this method [2,3,27]. The m-PD method utilises a crucible with a die at the bottom in which there is a centrally-placed nozzle.…”

“…Until recently, eutectics were mainly studied as structural materials because of their excellent mechanical properties. Mostly metal-metal eutectics were studied for this reason, but more recently, various studies of oxide-oxide eutectics [1][2][3][4][5] have begun to appear in the literature. Oxide-oxide eutectics have also been a recent focus of research into optical materials [6,7] and have been identified as materials which may act as photonic crystals [8,9].…”

Croissance de fibres polycristallines de composition eutectique AI2O3/Y3AI5O12 pour renforcement de composite

“…Les céramiques eutectiques possèdent une température de fusion et une résistance de rupture élevée, une bonne résistance à l'oxydation et surtout une bonne stabilité chimique [1][2][3]. Les oxydes composites ont été élaborés par la même technique que celle utilisée pour les systèmes métalliques, c'est à dire par solidification orientée du liquide eutectique.…”
