英文摘要	The influence of solution temperature on microstructure and mechanical properties of GH3625 alloy hot extruded tube were investigated by SEM, EDS, XRD, etc. The results indicated that 1 120 was a turning point in the microstructure and mechanical properties of alloys. When the solution treatment temperature was between 910 and 1 120, the grain hardness increased and the strength decreased slowly because of the pinning of NbC phase at grain boundary. When the solution temperature exceeded 1 120, the NbC phase was dissolved in a large amount, the pinning effect was weakened, the grain size increased rapidly, the hardness and strength of the alloy decreased obviously. With the increasing temperature, the dimples in alloy fractwre became large and deep and the plasticity gradually increased. When the temperature exceeded 1 120, there were mainly dimples in tensile fracture. In conclusion, the optimum solution treatment temperature of GH3625 alloy hot extrusion tube is 1 120. © 2018, Materials Review Magazine. All right reserved.
