Abstract

TiC-Ni₃Al composites have properties suitable for engine applications. Powder compacts with binder contents from 30-50 vol. % were fabricated by pressureless sintering under vacuum followed by low gas pressure isostatic pressing. The final microstructure consisted of a 'core-rim' structure with TiC cores surrounded by Ti(Cr,Mo,W)C rims. Room temperature flexural strengths ranged from >800 MPa up to 1150 MPa. These strengths were retained or actually increased up to temperatures of 500°C. The fracture toughness values were all > 12 MPa√m and as high as 27 MPa√m at Ni₃Al contents from 30 to 50 vol. %, respectively.
