A Discrete Dislocation Dynamics Study of Prior Particle Boundary Effects in Ni-based Superalloys

Abstract Ni-based superalloys produced via powder metallurgy (PM) undergo hot isostatic pressing (HIP) and subsequent forming operations, during which prior particle boundaries (PPBs) are formed and only partially eliminated. The residual PPB clusters strongly influence the mecha...
