Summary: By utilizing hot deformation and grain boundary diffusion processes, the coercivity of Ce-containing magnets can be improved. The analysis of microstructure reveals that the grain boundary phase formed by diffusion can weaken magnetic coupling and the optimized structure transforms the reverse domain from dendritic-like to dot scattered-like.

Summary: Significant enhancement in coercivity for hot deformed NdFeB magnets is achieved by doping R80Al20 (R= La, Ce, Dy, Tb) alloy powders. Microstructure analysis shows that Ce or La tends to distribute at grain boundary, while Dy or Tb and Al are located at grain boundary and surface. Magnetic isolation due to R-rich phase containing Nd, Ce or La, Al at the grain boundary contributes to coercivity enhancement, while strengthening magnetic anisotropy field of 2:14:1 phase due to Tb or Dy, and slight Al substitutions gives rise to significant coercivity enhancement.

Summary: There is a growing demand for high coercivity of NdFeB magnets with low heavy rare earth in emerging applications. In this study, dip-coating of 0.02 g and 0.09 g TbH3 on Tb-containing NdFeB magnets was found to enhance coercivity at room temperature. After diffusion, the highest coercivity reached about 30 kOe, suitable for traction motors of electric vehicles.

Summary: This study explores the potential of low-cost (Nd,La,Ce)-Fe-B hot deformed magnets for the application in variable-magnetic-force (VMF) motors. The results show that the hot-deformed magnets have the ability to adjust the coercivity and exhibit flat reversal curves. The microstructure observation and magneto-optical Kerr effect microscopy reveal the origin of the flat reversal curves. Additionally, the hot-deformed magnets have a relatively high remanent magnetization compared to sintered magnets, making them excellent candidates for VMF motor applications.

Summary: This study systematically investigated the effect of deformation temperature on grain refinement, texture strength, and magnetic properties of slow-deformed Nd-Fe-B magnets. The results showed that reducing the temperature led to gradual grain refinement and enhanced texture strength, resulting in increased coercivity and remanence of the magnets. Compared with traditional-sized magnets, near-nanoscale grain refinement improved coercivity by 57%, remanence by 10%, and energy product by 25%.

Summary: To inhibit the magnetic dilution effect of Ce in Nd-Ce-Fe-B magnets, a dual-alloy method is employed to prepare hot-deformed dual-main-phase (DMP) magnets using mixed nanocrystalline Nd-Fe-B and Ce-Fe-B powders. The lattice parameters of the RE2Fe14B (2 : 14 : 1) phase exhibit non-linear variation with the increasing Ce-Fe-B content due to the mixed valence states of Ce ions. The magnetic properties of DMP Nd-Ce-Fe-B magnets almost decrease with the increase of Ce-Fe-B addition, but the magnet with 10 wt% Ce-Fe-B addition exhibits improved intrinsic coercivity and temperature coefficients of remanence and coercivity compared to the single-main-phase Nd-Fe-B magnet.

Summary: We report on the microstructure, hard magnetic properties, and thermal stability of hot-compacted nanocrystalline (Nd0.85Ce0.15)15(Fe1-xCox)7(8)B(7) permanent magnets. The substitution of Fe by Co influences the grain boundary phase composition and degrades the coercivity at lower Co concentrations (x < 0.3). At higher Co concentrations (x >= 0.6), the absence of a grain boundary phase leads to strong magnetic coupling. Additional RE(Fe,Co)2, RE(Fe,Co)4B, and RECo5 phases gradually form with increasing Co concentration (x > 0.6). A new type of microstructure with nanograins and good thermal stability is observed at x = 0.4 and 0.6. In (Nd0.85Ce0.15)(15)(Fe0.4Co0.6)78B-7 magnets, the temperature coefficient of coercivity exceeds 0.3%/K within the temperature range of 300 K-500 K and 0.23%/K for the temperature range of 300 K-650 K, demonstrating the potential for designing highly thermal-stable permanent magnets.

Summary: Understanding the evolution of phase and microstructure is crucial for preparing high performance magnets. In this study, Ce-Fe-B magnets with different Ce contents were prepared via hot deformation. The results showed that the content of CeFe2 phase increased with increasing Ce content and its distribution pattern varied. The presence of CeFe2 phase improved the magnetic isolation effect and the overall performance of the magnets. In addition, the distribution of Pr and Cu elements differed between different regions of the magnets. The study concluded that the formation of (Pr, Ce)2Fe14B phase and increased magnetic isolation effects contributed to the improved coercivity, remanence, and magnetic energy product.

Summary: In this study, the eutectic Tb70Cu20Ga10 alloy was applied to a high magnetic performance NdFeB magnet, resulting in a 60.61% improvement in coercivity without any reduction in maximum energy product and remanence after diffusion. The magnetic vector potential of the magnet was analyzed using the general finite element method. The diffusion mechanism of the eutectic was discussed at various diffusion depths. Tb diffuses into the magnet, forming continuous Tb-rich shells and thin grain boundary phases, which greatly enhance coercivity. Cu, Ga, and O enrich the grain boundary, forming thin RE2(Fe, CuGaO)3 phases, which increase diffusion channels and recover microcracks near the magnet's surface. This diffusion alloy, Tb70Cu20Ga10, has a promising potential for developing high magnetic performance and low-cost sintered NdFeB magnets.

Summary: This study investigated the phase constitutions, ferroelectric, magnetic, and nanomechanical characteristics of BiFeO3 films with Dy substitution. The results showed that the BDFO films exhibited desired ferroelectric and ferromagnetic properties, and the hardness of the films was controlled mainly by the impeded propagation of dislocation by grain boundary. The findings suggest that the radius and magnetic moment of the Dy3+ ions play a critical role in the structural evolution and enhanced properties of the BDFO films.

Summary: This work investigates the formation of adjoining twin pairs (ATPs) at grain boundaries (GBs) in hexagonal close-packed (hcp) metals, focusing on the co-nucleation (CN) of pairs of deformation twins. A continuum defect mechanics model is proposed to study the energetic feasibility of CN of ATPs resulting from GB dislocation dissociation. The model reveals that CN is preferred over the nucleation of a single twin variant for low misorientation angle GBs. Further analysis considering GB character and twin system alignment suggests that CN events could be responsible for ATP formation even at low m' values.

Summary: This study investigates the behavior of electric-field induced antiferroelectric to ferroelectric (AFE-FE) phase transition and reveals the evolution of atomic displacement ordering as the cause for the transition behavior changing from sharp to diffuse. The novel semi-ordered configuration results from the competing interaction between long-range displacement modulation and compositional inhomogeneity, which leads to a diffuse AFE-FE transition while maintaining the switching field.

The key feature, shear strain rate of slip system, is identified based on crystal plasticity and incorporated into the loss function as physical constitutive equations. The introduction of physics constraints accelerates the convergence of the neural network model and improves prediction accuracy, especially for small-scale datasets. Transfer learning is performed to capture complex in-plane deformation of crystals with any initial orientations, including cyclic loading and arbitrary non-monotonic loading.

Summary: This study attempts to address the gap in cooling rates between thin film deposition and bulk metallic glass (BMG) casting by correlating the glass-forming range (GFR) determined from combinatorial materials chips (CMCs) with the glass-forming ability (GFA) of BMG. The results show that the full-width at half maximum (FWHM) of the first sharp diffraction peak (FSDP) is a good indicator of BMG GFA, and strong positive correlations between FWHM and the critical casting diameter (Dmax) are observed in various BMG systems. Furthermore, the Pearson correlation coefficients suggest possible similarities in the GFA natures of certain BMG pairs.
