Christon elastic fields in formation of bainitic ferrite lath structure
Engineering Education # 01, January 2013 DOI: 10.7463/0113.0529309 The authors analyze elastic fields of a separate prismatic loop and a set of loops (special cases of christon) modeling shear deformation media in shear bands with orientations of the borders close to {558} γ. It is shown that christons can act as dislocation nucleation centers for lath crystals forming the composition of bainite macroplate. The obtained results support the dynamic picture according to which individual laths of ferrite crystals are formed like martensite laths. However, between stages of forming ferrite rods there occurs carbon diffusion redistribution. As a result, there arise new areas of austenite which are beneficial for rapid growth of the next generation of lath crystals.
