Description

The compressive creep deformation microstructure of polycrystalline Ni3Al has been observed by transmission electron microscopy (TEM). left angle 110 right angle {111} and left angle 110 right angle {110} slip systems have been identified in primary creep. Dissociation of edge superpartial pairs perpendicular to the slip plane (both {111} and {110}) is common in crept specimens. The formation of this superdislocation configuration is thought to limit the extent of primary creep deformation. (orig.)
