Synthesis and behavior of bulk iron nitride soft magnets via high-pressure spark plasma sintering

Todd C. Monson et al.

Summary: This study synthesized dense bulk iron nitrides for the first time using spark plasma sintering, with the Fe4N phase showing potential as a new soft magnetic material. The density of SPSed FexN was found to increase with SPS temperature and pressure, with XRD revealing Fe4N as the primary phase.

On the mechanism of fatigue crack initiation in high-angle grain boundaries

Veronika Mazanova et al.

Summary: Studies have shown that the mechanism of fatigue crack initiation in high-angle grain boundaries is controversial. In this research, experiments were conducted on super-austenitic stainless steel Sanicro 25 to study the surface features that developed during cyclic loading with high strain amplitudes. The results revealed the presence of slip markings on the surface of grains, as well as extrusions and intrusions along the surface and normal to the grain boundaries. These processes ultimately weakened the grain boundary and led to the production of grain boundary cracks. These experimental findings challenge the theories suggesting a brittle-like origin of grain boundary cracks.

A mechanically strong and ductile soft magnet with extremely low coercivity

Liuliu Han et al.

Summary: Soft magnetic materials are essential for electrical applications and sustainable energy supply, as they can respond to changes in applied magnetic field with low energy loss. However, designing soft magnetic alloys with both high strength and low coercivity is a fundamental challenge. In this study, a Fe-Co-Ni-Ta-Al multicomponent alloy was developed, which contained ferromagnetic matrix and paramagnetic coherent nanoparticles. These nanoparticles impede dislocation motion, enhancing the strength and ductility of the alloy, while maintaining its soft magnetic properties.

Revealing Nanoscale deformation mechanisms caused by shear-based material removal on individual grains of a Ni-based superalloy

Dongdong Xu et al.

Summary: Shear-based material removal processes significantly affect workpiece surface quality and functional performance. In-situ SEM nano-cutting reveals crystal flow and lattice rotation below the cutting edge in polycrystalline Nickel superalloy. Deformed nanolayer forms within single grains, while nano-recrystallization and grain boundary bending occur in nano-cutting multiple grains.

High-frequency MnZn soft magnetic ferrite by engineering grain boundaries with multiple-ion doping

Mi Yan et al.

Summary: A high-performance MnZn ferrite has been reported by doping multiple ions at grain boundaries, achieving optimized power loss and initial permeability at high frequencies, better than existing products. This improvement is attributed to the weakening of magnetic exchange coupling at grain boundaries and the transition from multi- to mono-domain structures.

Design of Fe-based nanocrystalline alloys with superior magnetization and manufacturability

Hu Li et al.

Summary: A revolutionary nanostructure design concept was proposed in this study to improve the magnetic properties of Fe-based alloys by preforming dense nuclei and refining nano-structure via transient metalloid-rich interfaces. A novel alloy composition with superior magnetic properties was developed using only 4.6 wt.% light metalloids, showing great potential as a substitute for commercial bulk Si-steels in soft-magnetic applications.
