%X Based on the experimental result that Crand C segregated on the prior grain boundariesof austenite in overheated steels,causing theinheritance of fracture mode after re-austeni-tization,a thermodynamic analysis is conductedthrough the calculation of equilibrium segregationamount of Cr and C in grain boundary at 860and 1050℃ and the segregation kinetics of Cris also calculated.Thermodynamic calculationgives an evidence that the segregation of Crand C at grain boundaries may be regarded asone of the mechanisms of the fracture inheritancein overheated steels.
