Abstract

Two equilibrium diagrams, the single diagram and the double diagram, have been proposed for the system Fe—C and we cannot, as yet, decide upon which is the correct one. The single diagram assumes that graphite never separates directly from molten iron, which was, however, recently experimentally disproved by different workers including myself. It meets with a second difficulty as it represents a metastable equilibrium ; but a stable diagram for such an important alloy as Fe—C is required.
