Abstract

Abstract The dissimilar joint consists of 6061 aluminum and 110 copper with a Ni foil interlayer. The influence of Ni element on the interfacial microstructure composition and bonding properties of the Al/Cu bimetal was systematically investigated. The study results demonstrate that the Ni element can inhibit the diffusion of Al, and fine the microstructure of deleterious phase IMC at the interface zone. The tensile strength of joints with Ni foil increases firstly and then decreases with the increase of laser power, and the maximum is about 126.9 MPa which improves about 27.1 % than that of Al/Cu joints without Ni foil. The fracture surface mainly passes through the (Cu) solid solution and the Al2Cu + AlNi IMCs zone due to the presence of hard and brittle IMCs severely deleterious the joining strength of joints.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
