摘要
The δ-ferrite toγ-austenite phase transformation process of low carbon steel was observed in-situ under a confocal scanning laser microscope and the influence of manganese and chromium on the migration ofδ/γinterphase boundary during theδtoγphase transformation was studied.It was found that theδ/γinterphase boundary becomes unstable with the decrease of temperature,from planar to curved morphology during theδtoγphase transformation of Fe-0.08 Csteel and Fe-0.08C-0.8 Mn steel.But in Fe-0.08C-0.8Cr steel,theδ/γinterphase boundaries are stable with planar morphology during the wholeδ-ferrite toγ-austenite transformation.The destabilization ofδ/γinterphase boundary in Fe-0.08 C and Fe-0.08C-0.8Mn steels results from high degree of supercooling and sub-boundaries inγ,respectively.The stabilization ofδ/γinterphase boundary in Fe-0.08C-0.8Cr steel results from the slow diffusion rate of carbon atom induced by the addition of chromium.
