Physical and mechanical properties of mullite-whisker reinforced alumina composites

Conference Paper


Abstract


  • Reaction sintering and hot-isostatic-pressing (HIP) have been used for the compaction and densification of mullite-whisker-reinforced alumina composites. The effect of alumina matrix constraints on the in-situ transformation sequence in alumina-halloysite-AlF3 system was studied using differential thermal analysis. The physical and mechanical properties of the HIPed samples have been characterized in terms of bulk density, apparent solid density, porosity, Young's moduli, flexural strength, hardness and the fracture toughness.
