摘　　要：通过改变中间热处理冷却方式,研究了不同中间热处理工艺对一种铸造镍基高温合金组织和性能的影响。结果表明:试棒经1050℃×14 h中间处理后进行水冷、空冷和炉冷,力学结果显示三种冷却方式对断后伸长率和断面收缩率影响不大,均处于较低水平。但是,试棒的抗拉强度、屈服强度逐渐提高。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 1050℃×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.
