| Description |
Effect on microstructure, hardness, modulus, fracture toughness and oxidation behaviour of Al2O3-ZrB2 composite with different percentages of Titanium as diluents during the SHS reaction has been studied. It was observed that Ti addition leads to formation of different phases such as TiB2, ZrO2,TiB besides ZrB2 and Al2O3. The hardness and modulus were found to be around 21 GPa and 350 GPa, respectively for 10 wt.% Ti addition in dynamic depth indentation. Oxidation study of the sample having 25 wt.% Titanium showed no significant change in phase and mechanical properties after 700 degrees C oxidation. The toughness of 20 wt.% Ti sample showed highest fracture toughness. (C) 2013 Elsevier Ltd. All rights reserved
