Hot ductility of Inconel 617 alloy for A-USC turbine rotor application

doi:10.13251/j.issn.0254-6051.2024.01.015

Abstract

Abstract: Effect of different temperatures on high temperature tensile thermoplasticity of Inconel 617 alloy ingot was investigated. The results show that the Inconel 617 alloy has good thermoplasticity above 900 ℃, in which conditions the tensile fracture has obvious necking and the percentage reduction of area is more than 90%. With the increase of tensile temperature, the necking becomes more obvious, the dimples become more deeper, and the plasticity becomes more better. Dynamic recrystallization occurs locally during the tensile process. The higher the temperature, the more complete the recrystallization. The grains grow rapidly above 1200 ℃, and melting occurs at the fracture.

Key words: Inconel 617 alloy, hot ductility, dynamic recrystallization
