Abstract
Hot isostatic pressing (HIP) of nickel-based superalloys still suffer from some detrimental carbides precipitated along the prior particle boundaries (PPBs), resulting in the degradation of mechanical properties of superalloy parts. In this study, a novel asynchronous loading HIP strategy, elevating temperature to the highest value first and then raising pressure, was proposed for FGH4097 to overcome this industrial challenge. The results manifest this novel strategy paves the way for fabricating nickel-based superalloys with both significantly enhanced strength and ductility by in-situ eliminating carbides precipitated along PPBs during HIP process, further boosting HIP process as a potential technology for the near-net manufacturing of key components in aerospace field.
