Microstructure and high-temperature strength of Al2O3/Er3Al5O12/ZrO2 ternary melt growth composite

Microstructure and mechanical properties of Al2O3/Er3Al5O12 eutectic rods grown by the laser-heated floating zone method

“…11 Particularly, a strong selective emission band due to the Er 3+ ion in the Al 2 O 3 -Er 3 Al 5 O 12 eutectic matches up with the sensitive region of a GaSb photovoltaic cell, 12 allowing the application field of these eutectics to be extended. Binary and ternary eutectic studies of the Al 2 O 3 -ZrO 2 -Er 2 O 3 system have recently been reported [12][13][14] but experimental results on the mechanical properties of this material are still very limited.…”

Fabrication and microstructural stability of spark plasma sintered Al2O3/Er3Al5O12 eutectic

“…To overcome these disadvantages, ceramic oxide and non-oxides with binary and/or ternary eutectic compositions, produced by particular single crystal growth and melting processes, have been investigated extensively over the last decade [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. Of all the eutectic ceramics, Al 2 O 3 -based eutectics present superior creep and oxidation resistance, high temperature strength retention up to their eutectic temperature makes these eutectics an important candidate for high-temperature applications above 1500 1C.…”

Creep behavior and related structural defects in Al2O3–Ln2O3 (ZrO2) directionally solidified eutectics (Ln=Gd, Er, Y)

“…[6][7][8][9][10][11] Extension to ternary systems, by addition of zirconia for improving fracture toughness was also achieved. [12][13][14] The aim of the present work is to understand the mechanisms that control creep behavior of these materials at high temperatures (1400-1600 • C). In this purpose, specimens were prepared from various Al 2 O 3 -Ln 2 O 3 systems and crept using compressive tests.…”
