“…welding), does not change the current derivation. However in a more realistic model the complexity of the metallurgical bonding at the interface (see for example [24]) needs to be accounted for. To maintain the interface kinematically compatible, a stress gradient develops due to different constitutive properties of the two materials.…”

“…This ratio causes a thin clad layer in small diameters of CCA wire. In addition, the cross-section of CCA rod is reduced by several processes such as extrusion [29,30], spiral extrusion [31,32], caliber rolling [33,34], rotary swage [4,35,36] and cold wire drawing [37,38]. Meanwhile, during wire coiling, bending and stretching occur in the wire.…”

The copper clad aluminum (CCA) wire was fabricated by roll forming of copper foil around the aluminum wire rode. Non-continuous wire drawing (NCWD) was employed to study the effect of wire drawing parameters on ductility, micro-hardness and microstructure of the copper clad layer. The NCWD process continued without intermediate annealing until cracks were observed on the copper clad layer. The cracks appeared after a 78% reduction in the cross-section. The micro-tensile test was performed on specimens with transverse curvature to determine elongation. A modified correction factor was introduced to correct the effect of curvature size on elongation. The introduced correction factor proportional to the sample characteristics was between 0.7 and 1.4. Moreover, variations in the hardness and microstructure of the copper clad layer were investigated in the base metal and at the welding zone. Before beginning the wire drawing process for the annealed CCA wire with a diameter of 10.1mm and a Cu clad thickness of 0.48mm , the hardness, ductility, UTS and grain size of the clad layer were 87HV, 43%, 103MPa and 80 μm, respectively. At the end of NCWD for 10°a nd the 20% reduction ratio of the die, the diameter of CCA wire reached 4.7mm with a 0.22mm thickness of Cu clad. The hardness, ductility, UTS and grain size of the clad layer were 157HV, 2.9%, 325MPa and 8 μm, respectively.

Abstract. In recent years, the bicycle has become an environmentally friendly transportation. The bicycle can be divided into mountain bicycle and highway bicycle. Safe driving is the prior consideration. The bicycle braking system can be divided into oil pressure disk brakes and mechanical disk brakes. The brake disk system is one indispensable component of the safe system. In accordance to overall weight consideration of the bike, the brake disk should also focus on the lightweight design. This paper discussed an innovative brake disk forming technology for 6061 aluminum alloy by the rigid-plastic finite element analysis. The simulation parameters include geometric shapes of the brake disk and mold, die temperature, and friction factors. The stress and strain in forming, brake deformation and vibration modal analysis of brake disk in riding were studied. The paper is expected to offer some precision bicycle brake disk manufacture knowledge for industry.
