Summary

It is well documented that the microstructure (porosity, grain size, grain boundary composition, etc.) will influence the hardness of a ceramic. However it is not fully understood how these changes may affect the damage that results from the indentation process. In this effort, the density and grain size were varied in silicon carbide (SiC) ceramics. The materials were then subjected to Knoop and spherical indentations. After indentation the resulting damage in each material was assessed, compared, and correlated to the hardness and variations in the microstructure.
