dc.description.abstractDispersion of high temperature stable nanostructured Y2O3 in superalloys shows encouraging prospects in improving the mechanical, tribological and high temperature oxidation resistance [1]. Various ceramic oxides such as Y2O3, 50Y2O3-50Al2O3, 50Y2O3-50TiO2, 50Y2O3-50Cr2O3 (in weight%) has been synthesized by mechanical alloying for 20 h in flowing argon atmosphere (flow rate : 100 ml/min). The mechanically alloyed powders are compacted in a uniaxial hydraulic press to fabricate cylindrical pellets. The pellets are consolidated in controlled (Ar/H2) atmosphere to produce bulk compacts. The inert atmosphere synthesis and consolidation hinder the atmospheric oxygen ingress to improve the particle bonding and mechanical properties. The 20 h mechanically alloyed powders show mostly regular and ultrafine particles (<1 μm). The density of the pellets after compaction of all the oxides systems is in the range between 46-56%. Comparative studies of mechanical, tribological and high temperature oxidation of the oxides have been carried out. The present research will provide a roadmap to design ceramic oxides to achieve sustainable structural applications.en_US
