Carbon – Iron – Silicon

摘要: Because of the great importance ternary system C-Fe-Si in ferrous metallurgy a considerable amount attention has been devoted to phase relations, particularly those occurring solid state. The stable and metastable relations have raised much interest as basis steelmaking processes cast iron foundry industry. knowledge various transformations is therefore important for improvement composition treatment many engineering alloys steels. rapid solidification technologies attracted improving mechanical properties such strength, ductility, corrosion resistance magnetic which are far superior conventional irons. Numerous investigations done regarding liquidus surface, isothermal sections vertical systems. other on concern solubility measurements carbon γ liquid phases go always with activity measurements, determination diagram under high pressures kinetics studies austenite transformation martensite or bainite because these forecast steel. main experimental crystal structure, equilibria thermodynamics gathered Table 1.
