The class of titanium alloys are widely used in the fan and compressor stages of jet engines, due to their excellent strength to weight ratio and corrosion resistance. Near and alloys such as Ti-6242 and Ti-6-4 have exhibited sensitivity to cold dwell fatigue, resulting from the formation of commonly oriented particles called microtextured regions [1-2]. This paper will review some of the progress conducted under the Air Force funded Metals Affordability Initiative, program on the ICME of Microtexture Evolution and its Effect on Cold Dwell/High/Low Cycle Fatigue Behavior of Dual Phase Titanium Alloys [3].
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
