Abstract

Abstract: Thermal processing map of Inconel 600 alloy was obtained through thermal compression experiment by using Gleeble-3500 testing machine, and the microstructure corresponding to different zones of the thermal processing map was studied. Finally, the actual hot extrusion production was carried out by using the thermal processing window given by the thermal processing map. The results show that when the strain is 0.6, the thermal processing window is generally stable in the low strain rate region of 0.01-0.1 s^-1 and the high strain rate 10 s^-1 at 1150-1200 ℃. The actually produced pipe has a good macro morphology, and the microstructure is basically equiaxed recrystallized grains with twins, which are refined comparing with that of as-annealed alloy.

Key words: thermal processing map, superalloy, Inconel 600 alloy, microstructure
