Ionascu, C.Schaller, R.2010-11-302010-11-302010-11-30200810.4028/www.scientific.net/SSP.137.29https://infoscience.epfl.ch/handle/20.500.14299/61447WOS:000255428300005High temperature plasticity of fine-grained ceramics (ZrO2, Al2O3, etc) is usually associated with a grain boundary sliding process. The aim of the present research is then to improve the high-temperature mechanical strength of polycrystalline zirconia (3Y-TZP) through the insertion of multiwalled carbon nanotubes (CNTs) or silicon carbide whiskers (SiCw), which are susceptible to pin the grain boundaries. The effect of these nano-sized particles on grain boundary sliding has been studied by mechanical spectroscopy.polycrystalline zirconiacarbon nanotubessilicon carbide whiskersmechanical spectroscopyinternal frictionTetragonal ZirconiaGrain-BoundariesSuperplasticityCeramicsDeformationPolycrystalsSupportCreepHigh temperature mechanical loss spectrum of 3Y-TZP zirconia reinforced with carbon nanotubes or silicon carbide whiskerstext::conference output::conference proceedings::conference paper
