15 Sep 2021 | Contributor(s):: Elsayed, Omar Hesham
Advisors: Christopher Saldana, Thomas Kurfess, Katherine FuThe purpose of this study is to examine the effect of varying laser incidence angles on textural, microstructural and geometric characteristics of DED-processed materials, provide a more comprehensive outlook on participating laser-matter...
Effect of Hot Rolling and Intermittent Annealing on the Texture Evolution of Monotectoid BCC Zr-Nb
22 Jan 2018 | Contributor(s):: Dave, Tanvi
Advisors: Hamid Garmestani, Chaitanya Deo, Preet SinghIn the case of illicit trafficking of nuclear materials or interdicting nuclear debris, it is necessary to have the capabilities to intercept, collect, and analyze the nuclear material and determine its origin in a timely fashion. Nuclear...
Synthetic alpha-Ti Microstructures and Associated Transition Fatigue Responses
13 May 2017 | Contributor(s):: Matthew William Priddy, Noah Paulson, David McDowell, Surya R. Kalidindi
SummaryThis data set consists of over 3600 microstructure volumes and their associated local responses after three cycles of cyclic loading. This loading is expected to result in microstructure responses consistent with the transition regime between high cycle fatigue (HCF) and low cycle fatigue...
Towards a Taxonomy of Materials Science Imaging Challenges and Opportunities
08 May 2017 | Contributor(s):: Robert Pienta
This work investigates common imaging challenges faced by materials science practitioners. We investigate challenges from crowd-sourced images and investigate canonical and effective solutions to a number of common challenges we found.The work investigates:Contrast enhancementNoise reductionImage...
