Journal ArticleDOI
Real-time quantitative imaging of failure events in materials under load at temperatures above 1,600 °C
Hrishikesh Bale,Abdel Haboub,Alastair A. MacDowell,J. Nasiatka,Dilworth Y. Parkinson,Brian N. Cox,David B. Marshall,Robert O. Ritchie,Robert O. Ritchie +8 more
TL;DR: Using synchrotron X-ray computed microtomography, this work fully resolved sequences of microcrack damage as cracks grow under load at temperatures up to 1,750 °C, key ingredients for the high-fidelity simulations used to compute failure risks under extreme operating conditions.
Journal ArticleDOI
Damage evolution and failure mechanisms in additively manufactured stainless steel
Holly D. Carlton,Abdel Haboub,Gilbert F. Gallegos,Dilworth Y. Parkinson,Alastair A. MacDowell +4 more
TL;DR: In situ tensile tests were performed on additively manufactured austenitic stainless steel to track damage evolution within the material as discussed by the authors, and the results showed that porosity distribution played a larger role in affecting the fracture mechanisms than measured bulk density.
Journal ArticleDOI
Tensile testing of materials at high temperatures above 1700 °C with in situ synchrotron X-ray micro-tomography.
Abdel Haboub,Hrishikesh Bale,J. Nasiatka,Brian N. Cox,David B. Marshall,Robert O. Ritchie,Alastair A. MacDowell +6 more
TL;DR: The performance of the instrument has been demonstrated by characterizing the evolution of 3D damage mechanisms in ceramic composite materials under tensile loading at 1750 °C.
Journal ArticleDOI
Coded aperture imaging for fluorescent x-rays
TL;DR: The algorithm to develop and fabricate the free standing No-Two-Holes-Touching aperture pattern was developed and the algorithms to reconstruct the x-ray image from the recorded encoded pattern were developed by means of a ray tracing technique and confirmed by experiments on standard samples.
Proceedings ArticleDOI
High temperature x-ray micro-tomography
Alastair A. MacDowell,Harold Barnard,Dilworth Y. Parkinson,Abdel Haboub,Natalie M. Larson,Frank W. Zok,Francesco Panerai,Nagi N. Mansour,Hrishikesh Bale,Bernd Gludovatz,Claire Acevedo,Dong Liu,Robert O. Ritchie +12 more
TL;DR: In this paper, the authors present the results of high temperature experiments carried out at the x-ray micro-tomography beamline 8.3.2 at the Advanced Light Source.
