· JVASP-19818· TbAl2

TbAl2 is an intermetallic compound composed of terbium and aluminum, belonging to the rare-earth intermetallic family. This material is primarily of research and developmental interest rather than a widely commercialized engineering material, with applications being explored in high-performance aerospace and thermal management systems where rare-earth intermetallics offer potential advantages in strength-to-weight ratios and thermal properties at elevated temperatures.
