Strength and HRTEM microstructure at bond interface of aluminum/copper clad materials [PDF]
Keikinzoku/Journal of Japan Institute of Light Metals, 2009 It is known that it is difficult to bond dissimilar metals such as aluminum and copper or aluminum and iron using diffusion bonding, because an intermetallic compound is easily produced at the bond interface and bonding strength becomes low. However it is possible to bond the dissimilar metals using the vacuum roll bonding which performs hot rolling in
