Abstract: Abstract The precipitation hardening behavior of an Al-0.08Zr-0.014Sc-0.008Er-0.10Si (at.%) alloy was investigated utilizing microhardness, electrical conductivity, atom-probe tomography (APT), and compressive creep-measurements. This new composition, with a Sc:Zr atomic ratio of less than 1:5 represents… read more here.

DOI: 10.1016/j.matlet.2016.10.077
Abstract: Abstract The structural evolution of nano Cu-precipitates was studied with high-resolution transmission electron microscopy. 9R Cu precipitates were mainly multiple-twinned. However, the unusual 9R Cu precipitates with no twins were also observed. The 9R→face-centered tetragonal… read more here.
