中文摘要	RE2Si2O7 disilicates are promising candidates for oxidation resistant interfacial phase in SiC fiber-reinforced SiC matrix composites due to their good damage tolerance, good phase stability and compatible thermal expansion coefficients with SiC. We herein investigate the capacity and mechanisms of plastic deformation in beta-Lu2Si2O7 by a combination of Hertzian indentation experiment and transmission electron microscopy observation. A large amount of (11 0) deformation twinning, dislocations and slip bands are observed. For the common twinning mode, fewer atomic shuffle types, small shear strain, and low shear modulus in the twinning direction help explain the prevalence of this mode. (C) 2016 Acta Materialia Inc.
