This book was released on 1988 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: Single-crystal specimens of a Ni-base superalloy, PWA 1480, with a low pressure plasma sprayed Ni-Co-Cr-Al-Y coating, were tested in various 0.1 Hz fatigue and creep-fatigue cycles at 1015 and 1050°C. Creep-fatigue tests of the cp, pc, and cc types were conducted with various constant total strain ranges employing creep dwells at various constant stresses. Considerable cyclic softening occurred as was evidenced particularly by rapidly increasing creep rates in the creep-fatigue tests. The cycle time in the creep-fatigue tests typically decreased by more than 80% at 0.5 Nf.

This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: This program investigates the seemingly unusual behavior of single crystal airfoil materials. The fatigue initiation processes in single crystal (SC) materials are significantly more complicated and involved than fatigue initiation and subsequent behavior of a (single) macro crack in conventional, isotropic, materials. To understand these differences is the major goal of this project. Fatigue, Fracture, Single crystan, PWA 1480, PWA 1484.
