摘要

Microstructure evolution of two Nb-free and Nb-added low alloy steels during step-by-step ferrite transformation and the influences of Nb addition and prior austenite deformation were investigated by in situ neutron diffraction. The ferrite volume fraction estimated from the profile analysis is in a good consistence with that measured in the metallographic microstructure of a specimen quenched from the corresponding temperature. The changes in lattice plane strain during the step-by-step ferrite transformation were analyzed. The evident preferred orientation and residual strain were observed in the prior deformed austenite, especially in the Nb-added steel, which resulted in a higher starting temperature of ferrite transformation.
