Modelling of isothermal formation of allotriomorphic ferrite transformation at temperatures below the eutectoid in a medium carbon microalloyed steel

摘要

The present paper is concerned to the theoretical and experimental description of the isothermal growth kinetics of allotriomorphic ferrite in a medioum carbon vanadium- titanium microalloyed steel at temperatures below its eutectoid temperature and above any adiffusional transformation start temperature. Since pearlite is formed at these temperatures, the carbon enrichment of austenite far form the α/γ interface remains the same as the overall carbon content of the steel, and the soft-impingement effect can be neglected.
