    You can write a book review and share your experiences. Other readers will always be interested in your opinion of the books you've read. Whether you've loved the book or not, if you give your honest and detailed thoughts then people will find new books that are right for them.   The as-built surfaces of metallic parts made by additive manufacturing (AM) processes often contain notch-like features that serve as stress concentration sites where fatigue crack nucleation may occur. These notch-like features, which result from the surface roughness inherent to AM processes, should be considered in assessing the fatigue performance of AM by: 2.

    TMS It is a 3rd generation nickel-base single crystal supera lloy containing 3wt% Cr and 5wt% Re. This alloy has a good balance of creep strengths from intermediate to high temperatures; creep rupture lives at °C/MPa and °C/MPa are hours and hours,File Size: KB.   Engineering alloys such as Ni-based alloys, Al-alloys, and steels often contain non-metallic inclusions in their microstructures. These inclusions, which include oxide particles, carbides, and intermetallic particles, are introduced during component manufacturing processes such as casting, powder-metallurgy, or additive manufacturing methods. The presence of inclusions in the Author: Kwai S. Chan.

The fatigue limit stresses at 10 6 cycles were estimated using a step-loading method, with most testing performed at a frequency of f=50 Hz. Coaxing, also referred to as “under-stressing”, was a possible concern with a step-loading method, but it has been addressed elsewhere and has been shown to not be a concern with this Ti–6Al–4V product form.Cited by: These proceedings from the David L.

Davidson Symposium on High-Cycle Fatigue review the current research activities and assess the state-of-the-art in high-cycle fatigue, which has become a major concern in the design of engineering components and structures.This paper focuses on the static mechanical behavior of Ti-6Al-4V titanium alloy when exposed to several aggressive environments.

Flat samples, with very light notches (i.e. Kt = ), were tested under static loads, in inert environment and aggressive solutions: the samples gage sections were exposed to air and immerged in a NaCl solution (%) and in a methanol solution (95%).Author: Sergio Baragetti, Alessandro Medolago.
