The SEM analysis of decply etched specimens of Ni-base superalloys K38 and K19H+Ta in- dicates that both the primary morphologies under normal growth conditions and the final morphologies near equilibrium of MC carbides are octahedral blocks.The classification of MC crystal faces by means of PBC(Per...
