Research on Gradient Heat Treatment of Dual-property Disk for Alloy FGH96

摘要：

　　The transient temperature field in the dual-property disk of alloy FGH96 was investigated during the solution heating process of the gradient heat treatment by numerical simulation.The temperature curves for the different locations of the disk were attained.Then,the gradient heat treatment experiment was carried out,and the heat profiles were obtained.The numerical and the experimental results were almost consistent.The method of heat transfer for the bore of the disk was changed evidently through effective fixture design during the gradient heat treatment.The gradient of temperature (ΔT) can reach 121℃ or more,which lead to a supersolvus heat treated rim and subsolvus heat treated bore for the disk.
