摘要

An on-heating conversional model has been proposed to calculate the volume fraction of austenite in hypereutectoid steels from dilation strain. The transformation strain equation for austenite formation from ferrite and cementite was developed with lattice parameters modified to include alloying element effects. The conversional model was verified by comparing calculations with experimentally measured transformation temperatures and constituent volume fractions in the transformation temperature range for various heating rates. A continuous heating transformation (CHT) diagram was produced from model results.
