Indentation size effect of Al2O3 ceramics made by cold isostatic pressing and slip casting

The behaviour of indentation size effect (ISE) in Vickers hardness for alumina ceramics made by cold isostatic pressing (CIP) and slip casting (SC) is compared. To explain the origin of the ISE in alumina ceramics, the three approaches is proposed: the traditional Meyer Law ; proporcional specimen resistance (PSR) model and modified proporcional specimen resistance (PSR) model.
