· JVASP-142366· TaAl4Ni15

TaAl4Ni15 is a tantalum-aluminum-nickel ternary intermetallic compound belonging to the refractory metal alloy family. This material is primarily of research interest for high-temperature structural applications where the combination of tantalum's refractory character and nickel's strengthening effects offers potential advantages in extreme thermal environments. The specific composition reflects intermetallic ordering that may provide improved creep resistance and oxidation performance compared to conventional superalloys, though industrial adoption remains limited and further development is ongoing.
