Supply Description

The venture Carnot AimSCoRe goals to develop a recycling course of for Sm-Co everlasting magnets permitting the reuse of the recovered materials for the manufacturing of recent magnets. This entails acquiring an entire recycling course of, ranging from magnets to be recycled, of the 1:5 or 2:17 kind, and aiming to acquire sintered magnets, with shapes and dimensions adaptable for purposes.
Preliminary work carried out within the laboratory has highlighted particularities of the habits of Sm-Co magnets in the course of the software of a hydrothermal therapy. Particularly, it has been proven that the therapy results in the dissociation of the magnet right into a magnetic fraction and a non-magnetic fraction, that are simply separable. Moreover, these outcomes reveal potential hydration of the Sm-Co magnetic part in the course of the therapy.
The recruited researcher might be accountable for optimizing the hydrothermal therapy circumstances with the purpose of acquiring little or no degraded powders for sintering. For this, the habits of the Sm-Co magnets in the course of the course of have to be analyzed and characterised precisely, in relation with the magnetic properties of the powders obtained. The seek for optimum therapy circumstances would require the exact characterization of the structural and magnetic properties of the powders, to be able to establish and due to this fact management the reactions which happen for the completely different constituent phases of this kind of magnet.
The powders obtained might be compacted by sintering on the CRISMAT laboratory at ENSICAEN. The recruited researcher might be accountable for figuring out the optimum sintering circumstances which is able to make it potential to acquire supplies sufficiently dense to acquire magnets.

– Pulverization of Sm-Co magnets by hydrothermal or solvothermal therapy in a crystallization bomb.
– Research of the affect of pre-grinding the magnets on the effectivity of the method.
– Systematic characterization by X-ray diffraction of the powders obtained.
– Characterization by SQUID magnetometry and scanning electron microscopy of chosen powders.
– Optimization of therapy parameters (time and temperature) to be able to receive powders appropriate for sintering.
– Finishing up sintering assessments, and optimizing sintering parameters (temperature and strain)
– Characterization by X-ray diffraction and SQUID magnetometry of sintered supplies.

The GPM (Groupe de Physique des Matériaux, UMR CNRS 6634) is structured into 5 departments: Metallurgy, Microstructure Mechanics, Scientific Instrumentation, Useful Supplies and Nanostructures, Disordered Techniques and Polymers, and Thematic openings and improvements. It brings collectively 150 employees together with 60 Professors, Affiliate professors and Researchers, 30 technical employees and 60 PhD / PostDoct / Trainees. The laboratory is positioned on the Sciences and Engineering Rouen Normandie Campus (in Rouen), throughout the College of Rouen Normandie and INSA Rouen Normandie (7000m2).
The recruited researcher will work into the Useful Supplies and Nanostructures division, throughout the Useful Supplies and Magnetism crew, made up of 11 lecturers and researchers and a couple of PhD college students. The examine of the relationships between construction (microstructure, nanostructure, native atomic construction) and magnetism of supplies constitutes the framework of the analysis carried out throughout the crew. These actions are dedicated to the examine of utilized magnetic supplies.
