TiFe2

TiFe₂ is an intermetallic compound combining titanium and iron in a 1:2 stoichiometric ratio, forming a hard, brittle phase that belongs to the family of transition metal intermetallics. This material is primarily investigated in research contexts for hydrogen storage applications and as a reinforcing phase in titanium-iron composite systems, where its high stiffness and distinct elastic properties can enhance structural performance. TiFe₂ is notable for its potential in advanced alloy design where weight savings and thermal stability are critical, though its brittleness typically limits it to secondary reinforcement roles rather than primary structural duty.
