What is it about?
The production of amorphous materials with this technique is of current industrial interest for the construction of electrical transformer nuclei for the benefits in energy efficiency which can reach up to 80%. Scaling from a scientific scale to an industrial one, requires validation by experiments, the support of materials characterization techniques and numerical simulation. This work is a step toward the experimental characterization of the melt spinning technique for adequate numerical simulation.

Why is it important?
We have shown the capabilities of a 2D motion estimation technique like optical flow for calculating velocities for Chill-Block Melt Spinning. In addition, the temperature field measurements enable an increased spatial and temporal characterization of the process.
Perspectives
Chill block melt spinning (CBMS) process is widely used especially for the production of permanent magnets and metallic glasses. It is a rapid solidification process whereby a melt is ejected via a nozzle onto a rotating wheel solidifying in the form of a ribbon. It is empirically known that the cooling rate increases with decreasing ribbon thickness and therefore the material properties are dramatically improved. This work is a step toward the experimental characterization of the melt spinning technique for adequate numerical simulation, and show the capabilities of a 2D motion estimation technique like optical flow for calculating velocities for Chill-Block Melt Spinning. In addition, the temperature field measurements enable an increased spatial and temporal characterization of the process.
