“…Among the examples is e.g., the Al-Cu system; an Al-Cu composite sheet was reported to be up to 60% lighter and 30–40% cheaper than an identical sheet fabricated from Cu while maintaining comparable thermal and electric conductivity [ 32 ]. Moreover, from the viewpoint of mechanical properties, an Al-Cu clad composite can exhibit far higher fracture toughness than the individual metals [ 33 ]. Nevertheless, only limited attention has been given to preparation of clad composites via ECAP and ECAP-based methods.…”

The research and development of modern metallic materials goes hand in hand with increasing their lifetime via optimized deformation processing. The presented work deals with preparation of an Al/Cu clad composite with implemented reinforcing Cu wires by the method of twist channel angular pressing (TCAP). Single and double pass extrusion of the clad composite was simulated numerically and carried out experimentally. This work is unique as no such study has been presented so far. Detailed monitoring of the deformation behavior during both the passes was enabled by superimposed grids and sensors. Both the sets of results revealed that already the single pass imparted significant effective strain (higher than e.g., conventional equal channel angular pressing (ECAP)), especially to the Al matrix, and resulted in notable deformation strengthening of both the Al and Cu composite components, which was confirmed by the increased punch load and decreased plastic flow velocity (second pass compared to first pass). Processing via the second pass also resulted in homogenization of the imposed strain and residual stress across the composite cross-section. However, the investigated parameters featured slight variations in dependence on the monitored location across the cross-section.

Aluminum clad copper is frequently used as busbar conductor joint, electrical wires, communication wires and cables, armored cables, yoke coils, electronics chassis and cookwares [6,7]. In many applications Cu/Al clad can directly replace solid copper or aluminum.…”

Tri-layered Cu/Al-Mg-Si/Cu clad composite was cold roll-bonded, and its mechanical/electrical properties were studied. In the roll-bonded and aged Cu/Al-Mg-Si/Cu clad composite, neither interfacial reaction layer nor interface defects were observed. The strength as high as 415 MPa with the conductivity of 82 % IACS was attained in 3-ply lightweight Cu/Al-Mg-Si/Cu clad composite. The ductility and conductivity of clad composite are increased appreciably with heat treatment at 175 • C. After mechanical testing, the interface crack propagation and fracture in the well-bonded interface between metallic Cu and Al occurred in softer Al matrix. The increase of detached Al lumps onto the separated Cu side in clad composite heat-treated at 175 • C strongly supports that the interface bonding can be enhanced during aging of Al-Mg-Si alloy layer in Cu/Al-Mg-Si/Cu clad composite. The increased ductility in the aged Cu/Al-Mg-Si/Cu clad composite can be attributed to the enhanced interface bonding and precipitation in Al-Mg-Si layers.

The article is devoted to the study of Cu-Ni-Zn ternary alloy properties. German silver is applied in the instrument making industry, shipbuilding industry, and medical tool production. Furthermore, German silver is extensively used for domestic goods and costume jewelry. It is known that the aluminum and tin additions improve the Cu-Ni-Zn alloy flowing and casting mold fillability. It is a matter for the figurine and thin section casting production. That is why, using the experiment planning method we have studied the effect of Al and Sn alloyage and crystallization temperature on structure, casting characteristics and the casting characteristics of German silver. The study was realized by casting samples which were produced with lost wax method. Aluminum microadditives (0.4 %) have a positive impact on the casting mold fillability and improve markedly surface quality of casting samples. Tin leading into melt (about 4 %) ensure the marked growth of yield strength (by 65...70 %), while the elongation is maintained. The role of the mold temperature has a lesser impact on the yield strength. The mold temperature reduction from 550 °C to 450 °C leads to the grain size decrease and the little yield strength increase. Moreover, the surface condition measurement shows that aluminum and tin additions greatly reduce the castings surface roughness.
