| 520 | |a Abstract Directionally solidified $ Al_{2} $$ O_{3} $/$ Er_{3} $$ Al_{5} $$ O_{12} $/$ ZrO_{2} $ ternary eutectic ceramic in situ composite rods with length of 110 mm have been fabricated by laser floating zone melting. The microstructural characteristics of steady growth zone, initial growth zone and solid/liquid interface are investigated under high temperature gradient. In the steady growth zone, the eutectic spacing (λ) is rapidly decreased as increasing the growth rate (V), and the corresponding relationship between growth rate and eutectic spacing is determined to be λ = 11.14 × V−1/2. The temperature gradient has been measured to be about 5.3 × $ 10^{3} $ K/cm. In the initial growth zone, the melting process and temperature distribution are recorded by infrared thermal imager, and several unstable complex microstructures are observed. In the quenched zone, the regular eutectics with minimum eutectic spacing of 200 nm are obtained. Moreover, the solid/liquid interface during solidification shows convex interface morphology and the interface height is gradually decreased as increasing the growth rate. The eutectic growth behaviors at the center and edge of the as-grown rod are compared and discussed. | ||

In the quenched zone, the regular eutectics with minimum eutectic spacing of 200 nm are obtained. Moreover, the solid/liquid interface during solidification shows convex interface morphology and the interface height is gradually decreased as increasing the growth rate. The eutectic growth behaviors at the center and edge of the as-grown rod are compared and discussed.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Growth Zone</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Er2O3</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Eutectic Growth</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Interface Morphology</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Microstructure Morphology</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Su, Haijun</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Zhang, Jun</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Ma, Weidan</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Cao, Yewei</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Chen, Jun</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Liu, Lin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Fu, Hengzhi</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Journal of materials science</subfield><subfield code="d">Springer US, 1966</subfield><subfield code="g">52(2017), 10 vom: 07.

Directional solidification and growth characteristics of $ Al_{2} $$ O_{3} $/$ Er_{3} $$ Al_{5} $$ O_{12} $/$ ZrO_{2} $ ternary eutectic ceramic by laser floating zone melting |
| abstract |
Abstract Directionally solidified $ Al_{2} $$ O_{3} $/$ Er_{3} $$ Al_{5} $$ O_{12} $/$ ZrO_{2} $ ternary eutectic ceramic in situ composite rods with length of 110 mm have been fabricated by laser floating zone melting. The microstructural characteristics of steady growth zone, initial growth zone and solid/liquid interface are investigated under high temperature gradient. In the steady growth zone, the eutectic spacing (λ) is rapidly decreased as increasing the growth rate (V), and the corresponding relationship between growth rate and eutectic spacing is determined to be λ = 11.14 × V−1/2. The temperature gradient has been measured to be about 5.3 × $ 10^{3} $ K/cm. In the initial growth zone, the melting process and temperature distribution are recorded by infrared thermal imager, and several unstable complex microstructures are observed. In the quenched zone, the regular eutectics with minimum eutectic spacing of 200 nm are obtained. Moreover, the solid/liquid interface during solidification shows convex interface morphology and the interface height is gradually decreased as increasing the growth rate. The eutectic growth behaviors at the center and edge of the as-grown rod are compared and discussed. © Springer Science+Business Media New York 2017 |
