High pressure torsion (HPT) is presented as a new fabrication route to produce bulk Sm–Co magnets with strongly refined microstructure down the nanometer regime. The initial powders, based on compositions SmCo 5 , Sm 2 Co 7 and 17 are compacted subsequently deformed by HPT. microstructural evolution in dependence applied deformation parameters characterized electron microscopy effect of HPT phase stability monitored synchrotron X‐ray diffraction. An increasing amount strain leads stronger...
This work gives insights into processing and characterisation of bulk nanocrystalline FeCr materials. The investigated alloys, consisting 30, 50 70 at.% ferromagnetic Fe remaining anti-ferromagnetic Cr, are processed by arc melting subsequent severe plastic deformation high pressure torsion. physical similarities between elemental Cr in combination with the structure as-deformed necessitates advanced techniques for state: In-situ annealing synchrotron X-ray diffraction measurements as well...
Reducing the saturation magnetostriction is an effective way to improve performance of soft magnetic materials and reduce core losses in present future applications. The magnetostrictive properties binary Fe-based alloys are investigated for a broad variety alloying elements. Although several studies on influence Cu-alloying Fe reported, few have focused effect its behavior. High pressure torsion deformation promising fabrication route produce metastable, single-phase Fe-Cu alloys. In this...
