Based on the segregation of solute elements at solid-liquid interface, a coupled model of microsegregation and Ti-O inclusion precipitation during solidification of liquid steel is established by considering the finite diffusion of solute elements in both liquid and solid phases.

Based on conservation of mass in typical microscale control volume,which normally refers to half of secondary dendrite arm space,a semi-analytic microsegregation mathematical model for binary eutectic/peritectic alloys adapting to dendrite solidification mode has been erected,in which,diluent effects of back-diffusion and coarsening to liquid concentration are considered comprehensively.

The micro-segregation resulting in illternal crack in continuously cast slab is studied by using a mathematical model in which the transition of ferritic/austenitic solidification and the precipitation of MnS are considered.

The intemal crack susceptibility of carbon steel was studied by using a micro-segregation model in which the transition of fewhic / austenitic solidification and the precipitation of MnS were considered.

The solute redistribution severely affects dendritic morphology and micro-segregation formation.
