Iron and Fe–Si alloys (1, 2, 3 and 5wt.% Si) were reacted at 680°C with a gas mixture of 68% CO, 26% H 2 and 6% H 2 O (a C =2.9, pO2=2×10 −23 atm). Alloy reaction products consisted of internally precipitated SiO 2 , an external scale of Fe 3 C+SiO 2 and surface coke deposits containing cementite and silica particles. Coking and metal dusting...
Iron and Fe–10wt.% Ge alloy were exposed at 680°C to reducing, carbon-supersaturated CO–H 2 –H 2 O gas (a c =2.9). Iron grew into a cementite scale which disintegrated into nanoparticles as graphite deposited from the gas and grew into the Fe 3 C. The Fe–Ge alloy formed no Fe 3 C, and carbon deposited directly on the metal surface. As the graphite grew into...
