WebSep 23, 2015 · Nanocrystalline Cu-3 at.% Zr powders with ~20 nm average grain size were created with mechanical alloying and their thermal stability was studied from 550–950°C. Annealing drove Zr segregation to the grain boundaries, which led to the formation of amorphous intergranular complexions at higher temperatures. Grain growth was … Webtermed as grain boundary segregation engineering [4] or complexion engineering [5]. In this context, understanding the formation of different grain boundary chemical states and identifying their compositions is of importance to the material science community.
