摘要
Thermalshockresistantpropertiesofreactionsinteredbauxite-basedβ-Sialonbondedcorundumhavebeeninvestigated,andtheresultsarecomparedwiththoseofAl2O3basedcounterpart.Itisfoundtheyallhaveverygoodthermalshockresistance.Theirresidualstrengthratiosafteronethermalshockcycleat△T=1200℃and△T=1350℃are61%～73%and53%～65%respectively.Theircriticaltemperaturedifference(TSR)is600℃～800℃.TSRparametersarecalculatedbasedonthermalexpansion,modulusofelasticity,andfracturetoughnessdetermined.ThereasonsforimprovingTSRofthesecompositematerialsarediscussed.
