The tradeoff between the strength and fracture elongation in the high strength Cu-Fe alloys
has been a research focus recently. A Cu-10 wt.% Fe-0.5 wt.% Nb alloy was designed and
fabricated by casting and thermomechanical treatment to high strength and elongation.
Microstructure evolutions and properties variations of the studied alloy during cold-drawing
and cold rolling were investigated. After annealed at 400℃ for 1 h and further aged at 450℃
for 8 h, the ultimate tensile strength, elongation, product of the strength times the elongation …
