Microstructural Studies of in Situ Produced Filamentary Cu/Nb Wires

Microstructure evolution in Cu–1.54wt% Cr alloy during directional solidification

“…Fine particles of Cr-rich b phase homogeneously dispersed in Cu-rich a matrix are important for realizing such mechanical and electrical properties [1]. Recently, in situ composite copper alloys such as Cu-Fe [5], Cu-Ag [6], Cu-Nb [7] and Cu-Cr [1][2][3][4] have received much attention owing to their combination properties [2].…”

Structure of Kurdjumov–Sachs interfaces in simulations of a copper–niobium bilayer

“…The remarkable microstructural stability of the composites seen in these experiments suggests that CuNb interfaces are barriers to implantation-induced mixing, catalytic surfaces for rapid annihilation of Frenkel pairs created during energetic ion bombardment, sites for nucleation of nanometer-sized bubbles from the implanted He, and fast diffusion pathways for its subsequent escape from the composite. Because they posses such remarkable radiation damage resistance properties, CuNb compositesif manufactured in large quantities through processes such as cold drawing [8,9] -are attractive candidate structural materials for the next generation of nuclear reactors. Since, the selection of structural materials for these reactors will furthermore take into account factors such as corrosion resistance in specific environments as well as nuclear activation behavior, it is desirable to have the capability of predicting what other pairs of materials form interfaces that mitigate radiation damage as do the ones found in CuNb multilayer thin-film composites.…”

Microstructure and properties of Cu–11Fe–6Ag in situ composite after thermo-mechanical treatments

“…Binary deformation processed Cu-X in situ composites have attracted considerable attention during the past two decades because of their extremely high strength plus good electrical conductivity [1][2][3][4][5][6][7]. The Cu-Fe system is of particular interest because the solubility of Fe in liquid Cu is high at relatively low, industrially accessible temperatures and because the lower cost of Fe compared to other possible metals, such as Nb and Ag [8].…”
