英文摘要	The influence of solution treatment temperature on microstructural evolution and mechanical properties of the GH3625 alloy tubes in various states (hot extrusion, cold rolled and annealed) were investigated by microstructural characterization and performance tests (hardness test and tensile test at room temperature). The effects of solution treatment parameters (solution temperature, holding time and cooling method) on the microstructure and properties of GH3625 alloy tube were studied. The results showed that with the increase of solid solution temperature, the carbides in the matrix gradually dissolved. When the temperature was higher than 1130, the carbides in the matrix almost completely dissolved and the grains began to rapidly grow. When the temperature was at the ranges of 950 and 1250, grain growth activation energy reached at 208.60 kJ•mol-1. Hardness declined during the process of heat treatment temperature increased, and its values and the average grain size of the alloy kept in line with Hall-Petch relation. With the change of holding time, the grain growth rate first rapidly increased and then gradually became stable. When the holding time was 20 min, static recrystallization was basically completed. The change of hardness of the alloy was not obvious in this process. After air cooling and water cooling, the average grain size of the alloy remained unchanged and the hardness increased with the increase of cooling rate. © Editorial Office of Chinese Journal of Rare Metals.
