Title: Stress-strain behavior of alumina, magnesia-partially-stabilized zirconia, and duplex ceramics and its relevance for flaw resistance, K[sup r] curve behavior, and thermal shock behavior

Abstract

In this paper the stress-strain behavior for Al[sub 2]O[sub 3] of different grain size, for three different Mg-PSZ grades, and for various differently composed duplex structures is investigated and compared with their flaw resistance, K[sup R]-curve behavior, and thermal shock behavior measured in previous works. The experimental results seem to reveal that, for most materials, quasi ductility increases with increasing flaw resistance, increasingly pronounced K[sup R]-curve behavior, and increasing thermal shock retained strength. However, brittle ceramics can exhibit rising K[sup R]-curves, whereas pronounced quasi-ductile materials can exhibit flat K[sup R]-curves.
