Book Synopsis The Primary Creep Behavior of Single Crystal, Nickel Base Superalloys PWA 1480 and PWA 1484 by : Brandon Charles Wilson
Download or read book The Primary Creep Behavior of Single Crystal, Nickel Base Superalloys PWA 1480 and PWA 1484 written by Brandon Charles Wilson. This book was released on 2008. 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.
