Influence of microstructural size on the thermal shock behavior of Al2O3-Er3Al5O12 directionally solidified eutectics 2019 Access copy available to the general public Unrestricted We analyze the thermal shock resistance of directionally solidified eutectics. When quenching in water, the resistance starts to deteriorate with temperature differences in the range 260 to 300 K, almost independent of the microstructure size (or initial flexural strength). Unlike other strong, dense ceramics, the loss of strength is gradual upon quenching in boiling water. The onset of crack propagation seems to be controlled by the mismatch of the thermal and elastic properties of the component phases, while the length of the propagated cracks is limited by their quantity, which is estimated to scale approximately with the interface density. info:eu-repo/grantAgreement/ES/MINECO-FEDER/MAT2013-41045-R-EMITEME info:eu-repo/grantAgreement/ES/MINECO-FEDER/MAT-2016-77769R-FLASCERAMAT info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 5.079 2019 MATERIALS SCIENCE, MULTIDISCIPLINARY 70 / 314 = 0.223 2019 Q1 T1 METALLURGY & METALLURGICAL ENGINEERING 6 / 79 = 0.076 2019 Q1 T1 NANOSCIENCE & NANOTECHNOLOGY 34 / 103 = 0.33 2019 Q2 T2 2.046 2019 Condensed Matter Physics 2019 Q1 Materials Science (miscellaneous) 2019 Q1 Nanoscience and Nanotechnology 2019 Q1 Mechanics of Materials 2019 Q1 Metals and Alloys 2019 Q1 Mechanical Engineering 2019 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion (orcid)0000-0003-3480-398X Oliete, P.B.
