TL;DR: It is shown that nanocrystalline copper–tantalum alloys possess an unprecedented combination of properties: high strength combined with extremely high-temperature creep resistance, while maintaining mechanical and thermal stability, including in the aerospace, naval, civilian infrastructure and energy sectors.

TL;DR: In this paper, the authors used in-situ TEM heating experiments, atomistic modeling along with elevated temperature compression tests on a thermally stabilized nanostructured Cu-10.% Ta alloy to assess the microstructural manifestations caused by changes in temperature.

TL;DR: In this paper, a metastable Cu-1.% Ta solid solution was produced via mechanical alloying followed by subsequent consolidation into a bulk specimen using equal channel angular extrusion at 973 K (700 K).

TL;DR: The authors stabilise a nanocrystalline microstructure to suppress dislocation velocity and limit drag effects, conserving low strain-rate deformation mechanisms up to higher strain rates and temperatures.

TL;DR: A series of bulk nanostructured Fe-Ni-Zr oxide-dispersion-strengthened (ODS) alloys were synthesized using high energy mechanical alloying and consolidated using high temperature equal channel angular extrusion.
