Abstract
Joining Al alloy to steel has recently absorbed much attention to meet the requirement for the weight reduction of the transportation from an ecological point of view. As reviewed by Wallach and Elliot in 1981, it has long been accepted that the intermetallic compound (IMC) layer forming at the interface has a critical influence on the joint strength of the Al alloy to steel, and a serious impairment is brought about when its thickness exceeds a few μm. Several recent papers regarding the friction bonding of high-strength Al alloys such as 5000 and 6000 series to steel, however, have reported cases where joints exhibited a premature fracture at the interface on tensile test even when the IMC layer was no more than 1 μm in thickness. In order to reveal metallographic factors controlling the joint strength in these cases, the microstructure of the friction-bonded interface of the high-strength Al alloys to mild steel has been investigated on the basis of close observations with a TEM. It turned out that cracks on tensile test propagated through the IMC layer of 200 nm thickness, suggesting that the IMC layer much thinner than 1 μm was responsible for the brittle fracture in the interfacial region. It was also suggested that minor alloying elements in the Al alloy influenced significantly the kind of IMCs formed at the interface. The nano-scale investigation of the interfacial region will contribute greatly to the enhancement of the performance and reliability of the joint of Al alloy and steel.
