Literature Data

The T-x phase diagram Fe-S, in the version assessed by [1982Kub], reprinted in [Mas2] and accepted in a later assessment by [1988Rag], is shown in Figs. 1a, 1b. The system comprises a congruently melting phase Fe_1-xS, an incongruently melting phase FeS₂, a eutectic between Fe and Fe_1-xS and a monotectic between Fe_1-xS and S. There are metatectic and peritectic equilibria connected with the allotropic transformation of Fe near the iron side. A revised version of the central region of the diagram, made by [1992Gro], is shown in Fig. 2. The complex characteristic of this concentration range is evident. Different phases are formed which are superstructure variants of simple structures and are identified (as in Table 2...
