| 英文摘要 | GH4169 superalloy fibers with ultra-high strength and ultra-fine grain (UFG) were fabricated by cold de-formation and low temperature annealing, which provides a simple and effective method for preparation of UFG materials. In this study, the fibers were cold-drawn for 13 times and then cold-rolled 25 passes. Finally the annealing experiment is carried out on the cold-rolled samples. The fiber area was reduced by 97% and the grain size reaches 66 nm after cold deformation. In the subsequent annealing 450 & DEG;C for 30 min, the grain size was further reduced to 42 nm and the tensile strength of the fiber increases to about 2.05 GPa. The increase of the superalloy fiber energy storage and decrease of the curvature of the grain boundary lead to the low-temperature phase transformation. By controlling the annealing condition, these precipitation nanoparticles keep stable, the superalloy fibers are further refined and thus obtain higher strengthening superalloy fibers.& COPY; 2023 Elsevier B.V.
