A stable equilibrium diagram of the system Fe-C-Si was drawn standing on the stable equilibrium diagram of the system Fe-C proposed by the author in 1937*. Following the ternary equilibrium diagram by H. Jass the present author arrived at a somewhat different one.
The space model and its projections on the basal plane were drawn. The vertical sections of the space model parallel to Fe-C system keeping the content of Si constant at 1.0, 2.0, 2.6, 6.0, 7.0, 9.0, and 12.0%, and the horizontal sections at 700°C, 800°C and 1100°C were also drawn. Various figures were moreover given to illustrate the complex relations in the space model.
