Mathematical analyses of microsegregation and secondary precipitation during solification of steels

摘要: In order to predict segregations of solutes during solidification steels with more precision than previous microsegregation models such as Flemings - Brody equation and Clyne Kurz equation, finite difference method was utilized solve the Fick's law solute diffusion in combination thermodynamic equilibrium calculation at solid / liquid interface. control chemical compositions nonmetallic inclusions preferable properties steel products, mathematical analyses were done for prediction their change steels. most universal developed by present authors simulation softwares field phase diagram fully utilized. An improved path analysis also developped, which between adjacent segments each segment transformation.
