Abstract
We have investigated alloys in the Cr-Mo-Ti-C, Cr-Re-Ti-C, and Cr-Mo-R e-Ti-C systems in the eutectic (Cr) + (TiC) crystallization region. We found a four component quasibinary eutectic (Cr, Mo) + (TiC) with 4-8 at. % molybdenum content with melting point 1630 degrees C. Additions of 3-11 at. % Mo or 5-20 at. % Re to the base eutectic alloy Cr79Ti12 C9 doubles the Vickers hardness at 1000 degrees C (to approximately 20 00 MPa), and simultaneous introduction of molybdenum and rhenium (the alloy Cr51Mo8Re20Ti12C9) mises the hardness to 3000-3500 MPa.
