Based on the experimental result that Cr and C segregated on the prior grain boundaries of austenite in overheated steels,causing the inheritance of fracture mode after re-austeni- tization,a thermodynamic analysis is conducted through the calculation of equilibrium segregation amount of Cr and C in grain boundary at 860 and 1050℃ and the segregation kinetics of Cr is also calculated.Thermodynamic calculation gives an evidence that the segregation of Cr and C at grain boundaries may be regarded as one of the mechanisms of the fracture inheritance in overheated steels. 展开更多
