What is it about?
The aim of this work is to analyze the possibility of producing a joint by lamination of an Al-1050 plate and Fe78Si9B13(%at.) soft magnetic ribbon material obtained by a rapid solidification process by using the Melt Spinning (MS) technique.

Why is it important?
In the industry, a large number of magnetic circuits require welding and backing of Aluminum, due to its high thermal conductivity, low production cost, and weight. Due to the above, it is more common to find heat sinks composed entirely or largely of Aluminum in magnetic circuits. Thus, the present work is focused on lamination welds without the need for other materials, to increase the productivity in aluminum plates with magnetic parts.
Perspectives
It is possible to improve the magnetic efficiency achieved by proposing a set of modifications in different parameters in order to avoid the cracking of the magnetic ribbons during the collamination: - Decreasing heat treatment temperature and time prior to co-lamination may avoid temper brittleness. - Modifying the copper wheel speed and a controlled atmosphere in the melt-spun process. - Decreasing the lamination reduction coefficient (ε) and the substrate thickness would reduce the tensile stresses in the amorphous ribbons during collamination.
