| Abstract: | The hot-extrusion process of precipitation strengthened Nickle-based superalloy GH202 was studied.The optimized parameters were determined based on the rules of keeping thermal balance of deformation zone,and the special container and lubricant were used.The results show that the hot-extrusion process is suit for GH202 alloy.The grain of the seamless tube of GH202 alloy is finer and the properties are higher.The efficiency and yield markedly improves. |
| Keywords: | GH202 alloy seamless tube hot-extrusion process microstructure |
