· JVASP-20976· Nb3Co4B7

Nb3Co4B7 is an experimental intermetallic compound combining niobium, cobalt, and boron—a material class under active research for high-temperature structural applications. This ternary boride falls within the family of refractory metal borides, which are valued for extreme hardness and thermal stability, though processing and brittleness remain significant challenges compared to conventional superalloys. The material's appeal lies in potential weight-efficiency and high-temperature capability, making it of interest to aerospace and energy researchers exploring next-generation engine materials and wear-resistant coatings.
