英文摘要	The influence of solution treatment on microstructure and mechanical properties of GH3625 alloy sheet were investigated by OM, SEM, EDS, universal testing machine and Rockwell hardness tester and other means. The results indicated that the grains were equiaxed and there were a large number of annealing twins after the solution treatment. As solution treatment temperature was more than 1 130, the carbides in alloy almost completely dissolve into the matrix. Grain size was prompted by temperature increasing in the range of 890 to 1 190, and the energy (Qg) of grain growth was 227.18 kJ/mol. At different solution temperature, the grain size and room-temperature mechanical properties of GH3625 alloy accord with Hall-Petch relation. The main strengthening mechanism was fine grained strengthening. With the increase of temperature, the fracture mode of GH3625 alloy sheet was changed from brittle fracture to ductile fracture. © 2018, Materials Review Magazine. All right reserved.
