Precise compositional analyses at spatial resolution 690 °C with annealing at 420 °C for ∼24 h. We define a modified phase diagram that includes this two phase field with β-Fe x Se and δ-Fe x Se for 1.02 < x < 0.90 and a second two phase field with β-Fe x Se and α-Fe for 1.08 < x < 1.02. This revised phase diagram for Fe:Se ∼ 1.0 suggests that the peretectic transition nominally identified at x = 1.04 is not evident.
