摘要
The sequence of formation of plates in isothermal martensite transformation is taken into consideration in a modification of an earlier model of the isothermal kinetics. The spread of nucleation to untransformed grains and the continuing transformation within the already nucleated grains are simultaneously considered in computing the transformation curves. The discrepancy in the later stages of the transformation between the computed and the experimental curves found in the earlier model is reduced by the present modification. The results indicate that some austenite grains may contain no martensite at all up to 15 per cent total transformation, consistent with the metallographic observation in Fe-Ni Mn alloys that plates tend to be localised as clusters in the early stages of the transformation. © 1969.
