Indentation Size Effect of Conventional and Non- Conventional Sintered Al2O3 Ceramics
The objective of this study was to investigate and analyze the indentation size effect (ISE) using Vickers method of the alumina (Al2O3) ceramics sintered by conventional (electric kiln) and non-conventional sintering method (hybrid microwave kiln). The Vickers hardness was measured under the following loads: 0.98 N, 2.94 N, 4.90 N, 9.81 N, 29.42 N and 49.03 N. The ISE is analyzed using Mayer’s law, a proportional specimen resistance (PSR) model and a modified proportional specimen resistance (MPSR) model. Dependence of the hardness on test loads indicates Meyer’s index (n) that is less than 2 for alumina ceramics sintered by both sintering methods. High correlation coefficients confirm that all applied mathematical models are suitable for the data analysis, while the best correlation between measured values and mathematical models was achieved with the MPSR model with a correlation coefficient of 0.999.
