Rapid Quantification of Dynamic and Spall Strength of Metals Across Strain Rates
Suhas Eswarappa Prameela, Christopher C. Walker, Christopher S. DiMarco +8
The response of metals and their microstructures under extreme dynamic conditions can be markedly different from that under quasistatic conditions. Traditionally, high strain rates…
The Interplay Between Solute Atoms and Vacancy Clusters in Magnesium Alloys
Peng Yi, Taisuke Sasaki, Suhas Eswarappa Prameela +2
Atomic-scale calculations indicate that both stress effects and chemical binding contribute to the redistribution of solute in the presence of vacancy clusters in magnesium alloys.…
Strengthening magnesium by design: integrating alloying and dynamic processing
Suhas Eswarappa Prameela, Peng Yi, Yannick Hollenweger +6
Magnesium (Mg) has the lowest density of all structural metals and has excellent potential for wide use in structural applications. While pure Mg has inferior mechanical properties…
X-ray reflectivity with a twist: quantitative time-resolved X-ray reflectivity using monochromatic synchrotron radiation
Howie Joress, Shane Quinlan Arlington, Timothy P. Weihs +2
We have developed an improved method of time-resolved x-ray reflectivity (XRR) using monochromatic synchrotron radiation. Our method utilizes a polycapillary x-ray optic to create…
Design Analysis for Optimal Calibration of Diffusivity in Reactive Multilayers
Manav Vohra, Xun Huan, Timothy P. Weihs +1
Calibration of the uncertain Arrhenius diffusion parameters for quantifying mixing rates in Zr-Al nanolaminate foils was performed in a Bayesian setting [Vohra et al., 2014]. The p…
Interdiffusion of Ni-Al multilayers: a continuum and molecular dynamics study
Rong-Guang Xu, Michael L. Falk, Timothy P. Weihs
Molecular dynamics simulation of Al/Ni multilayered foils reveals a range of different reaction pathways depending on the temperature of the reaction. At the highest temperatures F…
