• A model experiment was made for study on the effects of temperature on the reaction rate in isothermal peritectic reaction in iron-carbon system by using a soliid/liquid diffusion couple method. Measurements of the variation in carbon concentration over δ, γ, and liquid phases show a decrease in the carbon concentration from the γ/liquid interface to the δ/γ interface and an equilibrium partition of carbon at both the interfaces. The γ-phase grows into both δ and liquid phases. A regression analysis of the thickness of the γ-phase, <I>x</I> (μm), with the reaction time, <I>t</I> (s), results in the following relations. <I>x</I>=36.6<I>t</I><SUP>1/2</SUP> at 1755 K <I>x</I>=54.7<I>t</I><SUP>1/2</SUP> at 1722 K <I>x</I>=71.0<I>t</I><SUP>1/2</SUP> at 1689 K These relationships imply that the peritectic reaction follows the parabolic law and that the reaction rate is higher at lower temperatures. It was found that about 90% of the γ-phase formed through the peritectic reaction is the transformation product from the δ-phase and about 10% the solidification product from the liquid phase.
