Bulk metallic glasses deform via slip avalanches.
James Antonaglia,Wendelin J. Wright,Xiaojun Gu,Rachel R. Byer,Todd C. Hufnagel,Michael LeBlanc,Jonathan T. Uhl,Karin A. Dahmen +7 more
TL;DR: The agreement between model and data across numerous independent measures provides evidence for slip avalanches of STZs as the elementary mechanism of inhomogeneous deformation in metallic glasses.
Journal ArticleDOI
Tuned critical avalanche scaling in bulk metallic glasses
James Antonaglia,Xie Xie,Gregory Schwarz,Matthew Wraith,Junwei Qiao,Yong Zhang,Peter K. Liaw,Jonathan T. Uhl,Karin A. Dahmen +8 more
TL;DR: A quantitative theory for the serration behavior of BMGs is presented, showing remarkable quantitative agreement with the slip statistics of slowly-compressed nanocrystals, and implying that material-evaluation methods based on slip statistics apply to both crystalline and BMG materials.
Journal ArticleDOI
Experiments and Model for Serration Statistics in Low-Entropy, Medium-Entropy, and High-Entropy Alloys.
Robert J. Carroll,Chi Lee,Che-Wei Tsai,Jien-Wei Yeh,James Antonaglia,Braden A. W. Brinkman,Michael LeBlanc,Xie Xie,Shuying Chen,Peter K. Liaw,Karin A. Dahmen +10 more
TL;DR: The proposed widely-applicable deformation mechanism is useful for deformation control and alloy design, and reminiscent of the Portevin-LeChatellier effect and time-temperature superposition in polymers.
Journal ArticleDOI
Shape and Symmetry Determine Two-Dimensional Melting Transitions of Hard Regular Polygons
Joshua A. Anderson,James Antonaglia,Jaime A. Millan,Michael Engel,Michael Engel,Sharon C. Glotzer +5 more
TL;DR: In this paper, a set of simulations investigates the behavior of a range of polygon-shaped particles and shows how body symmetry influences these phase transitions, leading to an exotic phase of two-dimensional matter that shares properties of both fluids and solids.
Journal ArticleDOI
Temperature Effects on Deformation and Serration Behavior of High-Entropy Alloys (HEAs)
James Antonaglia,Xie Xie,Z. Tang,Che-Wei Tsai,Junwei Qiao,Yong Zhang,M. O. Laktionova,Elena D. Tabachnikova,Jien-Wei Yeh,Oleg N. Senkov,Michael C. Gao,Jonathan T. Uhl,Peter K. Liaw,Karin A. Dahmen +13 more
TL;DR: In this paper, the serration behaviors of several high-entropy alloys (HEAs) from cryogenic to elevated temperatures were discussed, and the experimental results of slow compression and tension tests were compared with the predictions of a slip-avalanche model for the deformation of a broad range of solids.
