Abstract
Study of effects of tensile stress of 140 MPa on isothermal bainitic transformation product was conducted in this paper using transmission electronic microscopy. It was found that bainitic transformation units and ferrite plates which these units form, are much coarsened and their morphologies are greatly modified under the influence of this external stress. Attempt was made thermodynamically to explain that, the extra driven force for phase transformation provided by the external stress can help bainitic transformation units overcome more elastic strain energy in growth and result in larger final volume.
