Heat-Resistant Molybdenum Borosilicate Alloys Hardened with Titanium Carbides: Mo–Si–B–TiC (Survey)

Abstract

The review article is devoted to high-temperature borosilicate molybdenum alloys reinforced with titanium carbides MoSiBTiC. The article discusses phase diagrams, microstructure, production methods, mechanical properties, resistance to oxidation of these alloys, and protective coatings. It is shown that the long-term strength of MoSiBTiC alloys is superior at high temperatures to nickel heat-resistant alloys (NHRA) of the latest generations. Borosilicate molybdenum alloys MoSiBTiC can replace nickel heat-resistant alloys in many engineering fields, including in the production of cast parts for the hot section of aircraft gas turbine engines.
