Summary: Microstructure and magnetic properties of commercial Sm(CoFeCuZr)z magnets before and after post annealing treatment were studied. The results showed that the phases composition and orientation of the magnet did not change after post annealing treatment, but a substantial redistribution of Cu element within multiscale was observed. Furthermore, the post annealing treatment improved the thermal stability and magnetic performance of the magnet, but also caused a phenomenon of Cu depletion along the grain boundary that affected the magnetic domain reversal process and squareness of the magnet's demagnetization curve.

Summary: The atomic-scale structures of Z-plates in a Zr-alloyed Sm2Co17-type magnet were investigated using aberration-corrected STEM. Zr preferentially replaces dumbbell Sm to form (Sm1/3Zr2/3)Co3 Z-plates, which contribute to the enhancement of magnet performance. Different stacking types of Z-plates were observed, some of which exceed the thickness of double 2/3-stacking and degrade the oxidation resistance of the magnet. The diffusion-controlled mechanisms for the phase transformation from the 2:17R matrix to the 1:3R Z-plates were unraveled.

Summary: The improvement of high-temperature mechanical properties of W-Cu based composites was achieved through the combined effects of solid solution, dispersed nano-precipitation, and highly stabilized nanostructure in the W-Cu-Cr-ZrC composite. The high thermal stability of the nanostructure endowed the composite with a compressive strength of 1150 MPa at 900 degrees C, approximately four times higher than that of the binary coarse-grained W-Cu composite. The crucial role of microstructural stability of the W phase skeleton in the overall strength of the W-Cu based composites was revealed.

Summary: This study proposes an approach for toughening ceramic-based composites by modulating strain partition and stress distribution in phase-boundary regions. The concept of homogenizing lattice strain based on collective lattice shear is introduced to achieve high fracture toughness in ceramic-based composites. The feasibility of this strategy is demonstrated using ZrO2-containing WC-Co ceramic-metal composites. The crystal planes along the WC/ZrO2 martensitic transforming phase boundaries exhibit significantly larger and uniform lattice strains compared to conventional dislocation pile-up phase boundaries, enabling the composite to have high fracture toughness and hardness simultaneously. The homogenizing lattice strain strategy proposed in this study is applicable to a broad range of ceramic-based composites to achieve superior comprehensive mechanical properties.

Summary: Exfoliation of two-dimensional magnetic materials from non-vdW materials has become a topic of increased interest for the construction of 2D magnetic materials. Few-layer samples of non-vdW magnetic chromium tellurides, which possess high Curie temperatures, show promising applications in spintronics. The termination of the surface structures of few-layer chromium tellurides by either Cr or Te atoms remains under debate. Surface and exfoliation energy calculations reveal that the stability of the structures depends greatly on the chemical potential of Te atoms, and the few-layer sample with a Cr-terminated surface is easier to exfoliate than the one with both Te-terminated surfaces. Furthermore, the atomic number ratio of Cr to Te and the average magnetic moment of Cr atoms in few-layer samples can be used to identify different exfoliated structures.

Summary: Understanding the phase-transition processes of van der Waals (vdW) materials is crucial for controlling their performance and developing their applications. In this study, we investigate the structural transitions and Raman identifications of the monoclinic and orthorhombic phases of the layered vdW magnet CrI2. Our first-principles calculations reveal that each phase has a specific Raman spectrum, providing a reliable method to identify them. Additionally, the orthorhombic phase of CrI2 exhibits both ferroelectricity and magnetism simultaneously due to its unique interlayer stacking order, indicating its potential as a platform for sliding ferroelectricity and multiferroicity.
