FGH4096 Nickel-based superalloy was prepared by hot oscillating pressing (HOP) and hot pressing (HP). Compared with HPed sample, the sample prepared by HOP exhibits lightly higher yield strength and ultimate tensile strength, but greatly improved elongation. The elongation of the HOPed sample is as high as 36.9%, which is not only much higher than that of the HPed sample, but also higher than that of the sample prepared by hot isostatic pressing (HIP). The improvement in the elongation of the HOPed sample is likely due to the application of the oscillatory pressure, which enhanced inter-particle boundary sliding and/or plastic deformation during densification process.
