英文摘要The new Ni-Co-based superalloy featuring a "fusion structure" was produced utilizing electron beam smelting layered solidification technology (EBSL). Experimental examination of hot compression deformation with varied settings for EBSL and conventional duplex process melting Ni-Co superalloys was performed. As per the study, EBSL-Ni-Co superalloys exhibited enhanced recrystallization susceptibility during hot deformation. Furthermore, elevating deformation temperature, lowering strain rate, and augmenting strain collectively contribute to enlarging the volume fraction of dynamically recrystallized grains. Aberrant growth of grains occurred when the deformation temperature equaled gamma ' sub-solvus temperature and the strain rate was slower. Moreover, exceeding the gamma ' solvus temperature during deformation significantly increases the particle size of dynamic recrystallization (DRX) grains. The gamma ' phase can effectively modulate the DRX grain size through the pegging effect. Additionally, it was revealed that the presence of the fusion structure aids in the generation of continuous dynamic recrystallization, discontinuous dynamic recrystallization, and twinning-induced dynamic recrystallization while the alloy undergoes hot deformation. This mechanism promotes DRX granule formation and permits complete recrystallization. Ultimately, the fusion structure was identified as playing a catalytic role in the dynamic recrystallization process of the new Ni-Co superalloy.
