Abstract：By changing the cooling method of intermediate treatment,the influence of different intermediate heat treatment processes on the structure and properties of a cast nickel-based superalloy was studied.The results show that the test rod is cooled by water,air and furnace after intermediate treatment at 1 050℃×14 h.The mechanical results show that the three cooling methods have little effect on the elongation and section shrinkage after fracture,and all are at a low level.However,the tensile strength and yield strength of the test rod are gradually increased.
