Book Description
Qualitative TEM analysis revealed that PWA 1484 deformed by large dislocation "ribbons" spanning large regions of material. PWA 1480, however, deformed primarily due to matrix dislocations and the creation of interfacial dislocation networks between the [gamma] and [gamma]' phases. PWA 1480+ contained stacking faults as well, though they acted on multiple slip systems generating work hardening and forcing the onset of secondary creep. Xray diffraction and JMatPro calculations were also used to gain insight into the cause of the differences in behaviors.

Book Description
Interrupted tensile tests were conducted to fixed plastic strain levels in 001 oriented single crystals of the nickel-base superalloys PWA 1480. Testing was done in the range from 20-1093 C, at strain rates of 0.5 and 50%/min. The yield strength was constant from 20-760 C, above which the strength dropped rapidly and became a strong function of strain rate. The high temperature data could be represented very well by an Arrhenius-type equation, which resulted in three distinct temperature regimes. The deformation substructures could be grouped in the same three regimes.
