ANALYSIS OF THE ISE ON HARDNESS OF CIP-Al2O3 CERAMICS USING DIFFERENT MODELS
Objective of this study is to determine the effect of indentation load on the Vickers hardness of cold isostatically pressed (CIP) high purity alumina (Al2O3) ceramics. Specimen of a CIP-Al2O3 ceramics was embedded in DuroFix-2 Kit, polished, then indented at loads ranging between 0.1, 0.2, 0.5 and 1.0 kg with a Vickers hardness tester (n=30 per load). This study show that conventional hardness measurements are load-dependent, which implies a substantial influence of the indentation size effect (ISE). The ISE was described through the application of the Mayer Law, a proportional specimen resistance (PSR) model and a modified PSR model.
