Abstract

The phase stability of Cr₃C₂ in Al₂O₃/Cr₃C₂ composites sintered in as received Ar, purified Ar and vacuum were investigated. Test samples were cold isostatically pressed prior to pressureless sintering. Results suggested that phase conversion of Cr₃C₂ was eliminated by the reduction of oxygen content in sintering atmosphere. In addition, the porosities were substantially reduced, and strength and toughness were enhanced while sintered in vacuum.
