## Abstract Various heat treatments of the singleβcrystal nickelβbase superalloy SRR99 have been carried out to produce a wide range of initial Ξ³β² phase morphology. The cavitation damage has been studied after creep fracture at 850Β°C and stresses between 400MPa and 650 Mpa. The crep fracture surfac

A condition for destabilizing the raft structure has been deduced from elastic energy calculations with the concept of ''effective eigenstrain", where the effect of creep deformation is included in addition to the lattice mismatch. The calculations indicate that the 0 0 1 raft structure is stabilize
The evolution of orientation distributions of c and c 0 phases in crept Ni-base single crystal superalloys have been investigated by theoretical calculations with elastic-plastic models and by experiments. As creep deformation proceeds, the crystallographic orientation distributions for both phases
