An ε metastable phase of h.c.p. structure has been obtained in the alloy systems Fe-C, Fe-C-Sb by means of splat quenching. The ε phase is a solid solution the lattices constant of which increases with increase of Sb and C, but the value c/a is approximately constant. The ε phase of the Fe-C-Sb alloy is fairly stable thermally. DTA shows that the ε phase is non-dissociative below 125℃ and the addition of Si and Sb increases the stability. The grain size of the e phase is of the order of 10-1 micron. Our work verifies that of R.C. Ruhl and M. Cohen et al. concerning the e phase of the Fe-C-Si alloy. The topography of this ε phase has been studied by means of scanning and transmission electron microscopy.
