Microstructural Tailoring and Mechanical Properties of Ca α -Sialon Ceramics

摘要

The microstructure of Ca α-sialon ceramics can be tailored via the control of sintering conditions. This provides an excellent opportunity for studying the effect of microstructure on mechanical properties of ceramics. In this paper, a new approach to tailoring the microstructure of a selected Ca α-sialon composition is firstly presented. The process of microstructural evolution was analyzed in light of the relationship between the sintering parameters and the nucleation and growth rates.
