摘要	The hot compression behavior and tensile strength after compression of a new Ni-Co-based superalloy produced using electron beam smelting layered (EBSL) solidification technology were investigated. Isothermal compression tests were performed at temperatures of 1120 celcius and 1150 celcius, with strain rates of 1 s-1 and 0.01 s-1, reaching a true strain of 0.51. Tensile strength was evaluated at room temperature. The results revealed that this EBSL technology accelerates dynamic recrystallization (DRX), without compromising the strength of alloy. A significant correlation between the volume fraction of DRX and the strain rate was observed, with higher fractions at lower strain rates, leading to higher tensile strength. Additionally, at the same strain rate, the specimens compressed at 1120 celcius exhibited higher tensile strength due to undissolved gamma ' precipitates. After solution and aging heat treatment, the alloy maintained high tensile strength. The results suggested that the EBSL Ni-Co-based superalloy offers excellent prospects for practical applications.
