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 of steady-state creep.It is found that there exists a large amount of stacking faults,dislocation pairs 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 main creep fracture mechanism of(Fe_(60)Ni_(40))_3(V_(98)Ti_2).
