Abstract Scope |
Research on the manufacturing of permanent magnets has enjoyed renewed interest because of innovative developments in 3D printing. The main advantages of additive manufacturing are the ability to minimize waste, eliminate tedious machining, and create virtually unlimited sizes and shapes.
Traditionally, permanent magnet studies are performed via various techniques, with the 2nd quadrant demagnetization curve and hysteresis being the standard. We propose VSM-based magnetic measurements for 3D printed magnets that would be able to explore further and differentiate between seemingly identic magnet grades or temperature influence by exploring the interior of the hysteresis loop. These are the First Order Reversal Curves (FORC).
The non-compact character of these composite structures, with non-magnetic voids narrowly separating magnetic constituents is particularly suited for FORC measurements where interactions between magnetic components are exposed in the diagram’s shape and features. |
