Niobium-Base Refractory Alloys with Silicide and Carbide Hardening Current Status and Prospects

Аннотация

Achievements in the field of development of a new generation of refractory alloys based on the Nb – Si and Nb – C systems in the leading producing countries are reviewed. Results obtained for specimens of a patented domestic alloy with composition 45Nb – 16Si – 13Ti – 4Zr – 4Hf – 3.5Cr – 3.5Al – 9Mo – 2Y (at.%) are presented. Data on the structure and strength properties of the alloys based on the Nb – C system are discussed.
