英文摘要	The influence of cold deformation and heat treatment on microstructure and properties of the GH3625 alloy was studied through room-temperature compression test, mathematical model fitting, optical microscopy and Rockwell hardness and other means. Cold deformation constitutive equation of GH3625 alloy tubes was established. The results show that GH3625 alloy harde-ning law basically follows Hollomon equation, and the cold deformation was the main factor which affect the work hardening. With the increase of cold deformation extend, grain deformation degree raised, deformation uniformity of the grains gradually improved and average grain size decreased. With the increase of heat treatment temperature, the average grain size of the alloy first decreased and then climbed up. When the temperature was at the range of 1 100-1 250, grain growth activation energy reached 180.46 kJ/mol. Hardness declined with the increase of heat treatment temperature, the hardness values and the average grain size of the alloy kept in line with Hall-Patch relation. © 2017, Materials Review Magazine.
