The creep fracture behavior of intermetallic compound(Fe_(60)Ni_(40))_3(V_(98)Ti_2)has been studied.The variation of dislocation substructure was observed with TEM in the process ofsteady-state creep.It is found that there exists a large amount of stacking faults,dislocationpairs and also high density dislocation networks.SEM analysis of section near fracture sur-face points out that the intergranular crack due to coalescence of small cavities is the maincreep fracture mechanism of(Fe_(60)Ni_(40))_3(V_(98)Ti_2).
The creep fracture behavior of intermetallic compound (Fe_ (60) Ni_ (40)) _3 (V_ (98) Ti_2) has been studied. The variation of dislocation substructure was observed with TEM in the process ofsteady-state creep.It is found that there exists a large amount of stacking faults, dislocationpairs and also high density dislocation networks.
