英文摘要	In order to obtain GH3625 superalloy seamless pipe, the GH3625 superalloy seamless pipe with Phi 28 x 5.5 mm was developed through short-flow hot extrusion forming and cold rolling molding process. And a comprehensive evaluation to the microstructure and mechanical properties for GH3625 superalloy seamless pipe was conducted. The results show that hollow tube has been successfully extruded the GH3625 superalloy tube with Phi 43 x 9.5 mm under the condition of fixed extrusion speed of 50 mm/s, preheating temperature of 1150 degrees C and extrusion ration of 7.4. The alloy tube is composed of a small amount of deformation twin and a large number of equiaxed crystal mixed crystal structure, the average grain size is about 8.6, and the tensile strength at room temperature and elongation at break are 771 MPa and 52.33%, respectively, and have good cold working performance and mechanical properties. The performance of GH3625 superalloy seamless pipe after cold rolling and annealing is in accordance with ASTM-B163-04 international standard.
