“…The nickel-based superalloyGH4145(Inconel X-750)is an age-hardenable alloy and exhibits excellent mechanical strength, fatigue resistance and hot corrosion resistance. Thissuperalloy has a wide field of applications including gas turbine, rocket engine, aircraft structures, forming tools, pressure vessel and nuclear reactors [1][2][3][4][5].The deformation behavior of GH4145 superalloy has been studied by many investigators in the hot working regions [6][7][8][9], while little work was conducted in the cold and warm regions.Cold and warm working techniques offer great potential in the area of near-net shape and net-shape manufacturing technology [10]. However, the intrinsic workability of the material is inherently lower in the cold and warm working regions than in the hot working regime.…”

In this paper, uniaxial compression testsfor GH4145 superalloywere conducted on Gleeble-3800 at room temperature and 60°C with strain rates ranging from 0.5s-1 to 10s-1. No cracks were observed in all the specimens deformed from 10% to 70%, indicating that the GH4145 superalloy possesses great ductility under room temperature. The flow stress of GH4145 superalloywas not sensitive to strain rate deformed around room temperature and it decreased slightly with the temperature increasing. Dynamic recovery during deformation will start to balance the effect of work hardening when the true strain was arisen up to 0.4. Good agreement between the calculated and simulated temperature and strain shows that calculation method is accurate enough for the prediction.
