摘要	The thermal ductility and hot cracking sensibility of the forge and the rolling plates with 70 mm in thickness were studied by optical microscope (OM), scanning electron microscope (SEM), and Gleeble 1500 thermal simulation equipment. The results show that the forge and the rolling plates both have excellent thermal ductility; the samples taken from surface position present higher thermal ductility than those taken from middle position of the same plate. During the heating process, the rolling plate has higher thermal ductility than the forge plate at the lower temperature. With the increase of the temperature, the forge plate is characterized by higher thermal ductility compared with the rolling plate. However, during the cooling process, the forge plate indicates higher thermal ductility than the rolling plate. The fracture position features more smoother morphology, even the melt phenomenon exists at some positions. Besides, high hot cracking sensitivity appears in both the forge and rolling nickel alloy 690. And the crack number and length increase with the applied strain increasing.
