Outgassing of implanted He via short circuit transport along phase and grain boundaries in vapor co-deposited Cu-W nanocomposites

D Yadav, P Chen, S Xiang, Y Wang, JK Baldwin… - Acta Materialia, 2022 - Elsevier
We investigate the response of physical vapor co-deposited copper (Cu)-tungsten (W)
nanocomposites to helium (He) implantation. Nuclear reaction analysis (NRA) reveals that a …

Hierarchical tungsten-copper composite reinforced by a concrete skeleton of particulate and fibrous tungsten with coherent Cr precipitates in the copper matrix

L Zhuo, J Sun, Q Zhang, Y Zhang, S Liang… - Materials …, 2022 - Elsevier
The substitution of a precipitation-hardenable alloy of Cu-0.5 wt.% Cr for the widely adopted
pure Cu has been proposed for infiltration into the pre-sintered concrete skeleton of …

Crystallographic variant mapping using precession electron diffraction data

MH Hansen - Microstructures, 2023 - par.nsf.gov
In this work, we developed three methods to map crystallographic variants of samples at the
nanoscale by analyzing precession electron diffraction data using a high-temperature shape …
