· TiFeSb

TiFeSb is a ternary intermetallic compound combining titanium, iron, and antimony, belonging to the broader class of transition metal antimonides. This material is primarily of research and emerging applications interest, with potential in thermoelectric and magnetocaloric systems where the interplay of these three elements produces favorable electronic and thermal transport properties. The compound's mechanical and thermal characteristics make it a candidate for specialized high-performance applications where conventional alloys fall short, though industrial deployment remains limited.
