Bulk high-entropy hexaborides

Autor: Haoren Wang, Kenneth S. Vecchio, Jian Luo, Yi Liu, Huolin L. Xin, Timothy J. Rupert, Mingde Qin, Qizhang Yan, Chunyang Wang, Tianjiao Lei

Publikováno v: Journal of the European Ceramic Society. 41:5775-5781

For the first time, a group of CaB6-typed cubic rare earth high-entropy hexaborides have been successfully fabricated into dense bulk pellets (>98.5 % in relative densities). The specimens are prepared from elemental precursors via in-situ metal-boro

Intermetallic particle heterogeneity controls shear localization in high-strength nanostructured Al alloys

Autor: Tianjiao Lei, Esther C. Hessong, Jungho Shin, Daniel S. Gianola, Timothy J. Rupert

The mechanical behavior of two nanocrystalline Al alloys, Al-Mg-Y and Al-Fe-Y, is investigated with in-situ micropillar compression testing. Both alloys were strengthened by a hierarchical microstructure including grain boundary segregation, nanomete

In situ mechanical testing of an Al matrix composite to investigate compressive plasticity and failure on multiple length scales

Autor: Tianjiao Lei, Timothy J. Rupert, Jenna L. Wardini, Olivia K. Donaldson

SiC particle reinforced Al matrix composites exhibit high strength, high wear resistance, and excellent high-temperature performance, but can also have low plasticity and fracture toughness, which limits their use in structural applications. This stu

Bulk nanocrystalline Al alloys with hierarchical reinforcement structures via grain boundary segregation and complexion formation

Autor: Tianjiao Lei, Jungho Shin, Timothy J. Rupert, Daniel Gianola

Publikováno v: Acta Materialia. 221:117394

Grain size engineering, particularly reducing grain size into the nanocrystalline regime, offers a promising pathway to further improve the strength-to-weight ratio of Al alloys. Unfortunately, the fabrication of nanocrystalline metals often requires

Activation volume details from nonlinear anelastic deformation of a metallic glass

Autor: Tianjiao Lei, Michael Atzmon

Publikováno v: Journal of Applied Physics. 126:185104

At high stress, the viscosity of a metallic glass is non-Newtonian, and therefore the rate of anelastic stress relaxation is not linear in the applied stress. In this regime, one can obtain information on the details of the activation volume that are
