Abstract

Phase transformations in a creep-rupture tested specimen of nickel-base superalloy 740 were characterized by electron microscopy. During creep at 816°C, specimens developed chromium carbides and a complex suicide, the fee G-phase, along grain boundaries, and an hcp eta phase, having a Widmanstätten pattern of laths, across grains and grain boundaries. © 2004 Acta Materialia Inc.
