Abstract

The thermodynamics and kinetics associated with the peri-tectic transition have become greatly discussed topics. A high-temperature confocal scanning laser microscope has been used to observe the growth of γ-austenite along the pro-peritectic δ-ferrite/liquid-Fe boundary and to measure the rate at which this occurs. It was found, for Fe-18 wt.% Co, Fe-19 wt.% Co, and Fe-20 wt.% Co alloys, that the reaction rate increased with increasing undercooling over the temperature range observed and that there was no discernible difference in rate between the three alloys. The growth rate dependence on undercooling was found to be ν = (62.82 ΔT2–70.90 ΔT + 149.04) ± 15.61 μm s–1. This rate compared well with the growth model proposed by Bosze and Trivedi when the uncertainties in available phase diagram information were considered.
