In this study, the Cu-1Cr-0.2 Zr (wt%) alloys with trace Mg element (0.05 wt%) were prepared
by a two-step cryorolling and aging (CRA) process. The effects of the two-step CRA and Mg …

Improving high-temperature strength and resistance to high-temperature softening is an
important method to promote the application of high-performance Cu-Cr-Zr alloy in fields …

Understanding dislocation behavior is considered an effective way to design high

The roles of Hf element in the mechanical properties, deformation mode and orientation
evolution of the Cu-0.4 Cr-0.2 Zr-0.2 Hf (wt.%) alloys were investigated using both ex-situ …

In this work, the microstructural evolution and strengthening mechanisms of pure copper and
Cu–Ag alloys subjected to cold rolling were experimentally investigated. Significant strain …

Understanding the interactions between solute atoms and dislocations is essential to
developing metallic materials for simultaneously high strength and ductility. Previous studies …

The mobility of edge dislocation in Cu–Ni solid solution alloys within a wide range of
temperatures 100–1100 K and Ni concentrations 0–30 at.% is studied by molecular …

A combination of high strength and high ductility has been observed in multi-principal
element alloys due to twin formation attributed to low stacking fault energy (SFE). In the …

Abstract The trace Hf element (0.2 wt%) was added into the Cu-0.4 Cr-0.2 Zr (wt.%) alloy to
achieve synchronous improvements in strength, ductility and electrical conductivity. The …

Abstract A Cu-0.48 Cr-0.20 Nb-0.27 Zn (wt.%) alloy with excellent comprehensive
