摘要：
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. (C) 1999 Elsevier Science Limited and Techna S.r.l. All rights reserved.
