Ferrite reaction
WebIn eutectoid transformation processes, wherein both ferrite and Fe3C (or an alloy carbide) form either co-operatively or competitively, the carbon diffusion distance tends to diminish rapidly with decreasing temperature, while the reverse situation obtains during the pro-eutectoid ferrite (and cementite) reactions. WebThe ferrite undergoes two progressive reactions with the gypsum: in the first of the reactions, the ettringite reacts with the gypsum and water to form ettringite, lime and …
