An Investigation on the Titanium-Iron-Carbon System (1st Report). On the Titanium-Iron System

Yôtarô Murakami, Hirozô Kimura and Yoshio Nishimura


Abstract:

The solid solubility ranges of the two intermetallic compounds,TiFe and TiFe2,in the titanium-iron binary system were studied by microscopic examination and X-ray analysis. The solid solubility range of the TiFe phase extends from 52 weight pct to 54 weight pct of iron and its solid solubility curves are nearly vertical against falling temperature,and the lattice parameter decreases with increase of iron concentration. The TiFe2 phase extends as widely as from 68.5 weight pct to 77 weight pct of iron at the temperature of about 1300°,and narrows down moderately with dropping temperature, and its lattice parameters c and a decrease with increase of the iron content while the axial ratio, c/a, remains approximately constant at 1.633.
