Description
SiAlONs are ceramic materials with a range of technically important applications, from cutting tools to wear parts and the properties of SiAlONs can be tailored for specific applications. Wear performance of the cutting tools are governed by material properties which are affected by microstructure. Microstructure of SiAlONs can be controlled by types and amount of liquid phase sintering additives, which affect the distribution and crystallinity of intergranular phase, remnant of the additives after sintering. In this presentation, the effect of various types of sintering additives on the
intergranular phase chemistry and microstructures will be reported for SiAlONs that are developed to be used in machining of different type of materials.
