The structure and properties of multicomponent eutectic alloys on the base of chromium and titanium carbide

摘要

The alloys of the Cr-Mo-Ti-C, Cr-Re-Ti-C and Cr-Mo-Re-Ti-C systems were investigated in the field of eutectic + crystallization. The four compo- nent quazibinary eutectic + for the molybdenum content 4-8 /100 (at) with 1630 °C melting temperature was found. The additions of 3-11 (/100) at. Mo or 5-20 /100(at.) Re to the basic eutectic alloy Cr_79Ti_12C_9 raise double the Vicker's hardness at 1000 °C (approximately to 2000 MPa) and the joint introduction of molybdenum and rhenium(alloy Cr_51Mo_8Re_20Ti_12C_9) inereases the hardness to 3000-3500 MPa.
