IN SITU OBSERVATION ON FORMATION OF BASKET DURING BAINITIC TRANSFORMATION

摘要

By means of riM-190 hot-stage microscopy,the in situ observation of α-β transformation in12Cr2MoWVTiB steel has been carried out.The sequence of the growth of ferritic needlescomposing bainitic basket has also been determined.According to the crystallographic analy-sis a multislip system transform model concerning the formation of basket has been proposed.
