We report the effect of grain boundary diffusion of the Nd-Cu eutectic phase and the influence of Nb on the microstructure and magnetic properties of Nd-Fe-B melt-spun ribbons. The Atom probe tomography analysis indicated the presence of Nb clusters

This paper presents methods and approaches that can be used for production of Sm-Co-Fe-Cu-Zr permanent magnets with working temperatures of up to 550 °C. It is shown that the content of Sm, Cu, and Fe significantly affects the coercivity (Hc) value

Nanorods of Gd2O3 with 5 at.% Nd3+ and 5 at.% Er3+ ion substitution at Gd-site have been synthesized using a template-free and surfactant-free hydrothermal method. The samples have MnFeO3-type cubic crystal structure (space group Ia-3, N 206, cI80) a

Laves phase rare earth intermetallic compound ErAl2 (Cubic, MgCu2-type) has been prepared by melt-spinning process. Analysis of powder X-ray diffraction data of melt-spun ErAl2 yields crystallite size of about 54 nm. Transmission electron microscopy

We recently reported that the columnar grain width of Cr2AlC MAX phase coatings increases during oxidation (4 h at 1120°C) by 80%, while for 0.7 at.% Si additions to Cr2AlC, coarsening of only 12% was observed. Here, we use nm scale compositional an

Dual-phase high-entropy alloys (DP-HEAs) with transformation induced plasticity (TRIP) have an excellent strength-ductility combination. To reveal their strain-rate sensitivity and hence further understand the corresponding deformation mechanisms, we

Fe-Si-B-Nb-Cu alloys are attractive for high frequency applications due to their low coercivity and high saturation magnetization. Here, we study the effect of stress annealing on magnetic microstructure in Fe73.5Si15.5B7Nb3Cu1 using off-axis electro
