ABSTRACT
Considering ferrite grain size in the base metal, the prediction model for Ac₃ temperature and prior austenite grain size at just above Ac₃ temperature was proposed. In order to predict Ac₃ temperature, the Avrami equation was modified with the variation of ferrite grain size, and its kinetic parameters were measured from non-isothermal data during continuous heating. From calculation using a proposed model, Ac₃ temperatures increased with increasing ferrite grain size and heating rate. Meanwhile, by converting the phase transformation kinetic model that predicts the ferrite grain size from austenite grain size during cooling, a prediction model for prior austenite grain size at just above the Ac₃ temperature during heating was developed.
