Summary: This study systematically investigates the effect of cooling rate on physical properties of Fe-6.5wt%Si alloy by changing melt-spin wheel speeds, which significantly affect the solidification temperature profile, ordering, microstructures, textures, hardness, and magnetic properties. The research shows a critical cooling rate at around 1.7 x 10(5) K/s, below which the material embrittlement occurs due to the increase of ordered phases.

Summary: Based on rapid solidification technology, Cu is incorporated into soft magnetic materials to achieve grain refinement. Cu dosage not only refines the average grain size to 8.7 µm but also improves the continuity and consistency of Fe-6.5 wt % Si steel strip. This is mainly attributed to Cu-rich particles precipitating at the grain boundary, which inhibit grain growth and improve magnetic and mechanical properties. The addition of 1.5 wt % Cu results in excellent magnetic properties and about 11% failure plastic deformation for the steel strip. This technology also has reference value for modifying the mechanical and magnetic properties of other metal materials.

Summary: LaFe11.8Si1.2/16wt%La65Co35 samples were prepared by spark plasma sintering (SPS) and subsequent annealing. The La65Co35 binder increased the 1:13 phase content, and the alpha-Fe phase formed and disappeared during annealing. The sample annealed for 0.5 h showed a distinct core-shell structure, desirable table-like (-Delta S-M) -T curve, and higher RC value. The diffusion of Co was hindered by the growth of La5Si3 phase. Samples annealed for 24 h achieved larger (-Delta S-M)(max) and (sigma(bc))(max) values. The method combining SPS and diffusion annealing is promising for preparing La-Fe-Si based magnetocaloric composites with good properties.

Summary: The Nd13.65Fe73.55B5.6Co6.6Ga0.6 ribbons with mixed platelet-shaped and equiaxed grain microstructure were obtained after pressureless annealing. The growth of equiaxed grains into platelet-shaped grains is mainly driven by temperature field rather than press field, with the help of the Nd-Ga-rich molten liquid phase at the grain boundaries. The crystallization of Nd-2(Fe,M)14B grains improves the coercivity of the ribbons.

Summary: The addition of Cu in the range of 0-1.0 wt% affects the magnetic induction and iron loss of 6.5 wt% Si electrical steel. Cu addition up to 0.7 wt% can slightly increase magnetic induction B50, while the iron loss decreases with increasing Cu addition up to 0.5 wt% before increasing again. The optimum range for achieving the best magnetic properties for 6.5 wt% Si electrical steel is found to be 0.3-0.5 wt% Cu.

Summary: Fe-6.5 wt%Si alloy is a promising soft magnetic material for transformers and motors. This study investigates the ductile to brittle transition (DBT) behavior of air-cooled and water-quenched Fe-6.5 wt%Si alloy through three-point bending tests. The water-quenched specimen exhibited a lower DBT temperature than the air-cooled specimen, and the DBT activation energies were calculated. The differences in DBT behaviors were attributed to the presence of ordered structures in the air-cooled specimen. A numerical model was also developed to predict DBT temperatures based on strain rate-temperature dependence.

Summary: This study comprehensively assessed the anatomy and geometry of the mitral annulus, coronary sinus, and left circumflex artery in patients with mitral regurgitation using three-dimensional reconstruction of cardiac CT images. The results showed that patients with mitral regurgitation had a larger mitral annulus perimeter index, increased coronary sinus diameters, and greater posterior mitral annulus radian. The distances between the coronary sinus and mitral annulus were significantly different among the groups. Patients with mitral regurgitation had a smaller coronary sinus-mitral annulus plane angle during systole. The findings of this study are important for improving the results of transcatheter mitral annuloplasty and enhancing device design.

Summary: The hot compression test was conducted on the as-cast TNM alloy, with a true strain of 0.9, at temperatures ranging from 1100-1250 degrees C and strain rates of 0.001-1 s(-1) using a Gleeble3800 thermal simulation testing machine. The stress-strain curves were used to evaluate deformation resistance and uniformity, while microstructure analysis was performed using scanning electron microscopy and transmission electron microscopy. The study found that lower strain rates resulted in more uniform deformation within the specimen, and that different microstructures were achieved at different strain rates and temperatures. The deformation mechanisms were analyzed and empirical hot processing maps were used to optimize the processing parameters, with the recommended parameters being 1200-1250 degrees C and 0.1-0.01 s(-1) for achieving a uniform fine grain structure without specimen cracking.

Summary: The tensile properties and deformation behavior of a TNM-based alloy microalloyed with W, C, and Y were systematically investigated. The addition of trace microalloying elements significantly refined the microstructure and improved the strength and ductility of the alloy. High-density dislocations, deformation twins, and twin intersections were observed near the tensile fracture, and dislocation dissociation promoted the formation of deformation twins. The twin intersection hindered dislocation movement and relieved stress concentration, enhancing the tensile performance of the alloy.

Summary: A Monte-Carlo-assisted phase field model is proposed to simulate grain growth in metals and alloys. The simulation time is connected to real time through an experimental data-based kinetic model. Site selection probability is introduced to simulate grain structure evolution under non-isothermal conditions. The study comprehensively reproduces the grain evolutions during the welding process, and the computed results are compared to experimental data for two alloys. The application of real-time-temperature based phase field simulation shows significant promise for understanding grain structures during material processing.

Summary: An in-situ dual morphology carbide and boride reinforced Ti-47.7Al-7.1Nb-2.3 V-1.1Cr (at%) alloys were fabricated with nano-B4C addition by spark plasma sintering (SPS). The addition of 0.2 at% nano-B4C significantly refined the lamellar colony size from 126 +/- 45 μm to 45 +/- 15 μm and improved the ultimate tensile strength (UTS) by 105 MPa. The improvement in tensile property is attributed to the multiple strengthening induced by Ti2AlC micron/nanoparticles and TiB2 nanoparticles.

Summary: The microstructure instability of high Nb-TiAl alloy at high temperature severely limits its use in complex environments. Refractory metal W nanoparticles can effectively stabilize the microstructure due to their high melting point. Additive manufacturing technology can further refine the microstructure. In this study, the flow of melt during selective laser melting (SLM) process is simulated, and it is found that the scanning speed affects the melt flow behavior. By using SLM to prepare nano-W composite TiAl alloys, higher scanning speeds result in more uniform dispersion of nano-W particles. The nano-W particles act as heterogeneous nucleation sites and inhibit the growth of columnar grains, leading to the formation of randomly oriented equiaxed grains microstructure.

Summary: By using directional solidification technology, the plasticity and strength of TiAl alloy at room temperature and high temperatures can be effectively improved. However, ensuring the lamellar orientation is parallel to the growth direction poses various difficulties. This paper reviews two fundamental thoughts for lamellar orientation control: using seed crystals and controlling the solidification path. Multiple specific methods and their progress are introduced, and the advantages and disadvantages of different methods are analyzed. Novel ways of controlling the lamellar orientation and future development are also discussed.

Summary: The magnetic domain structures and martensite microstructures of porous Ni2MnGa Heusler alloys with different circle-shaped and ellipse-shaped pores were studied using the phase field method. The study proposed a mesoscopic mechanism to simulate the influence of pores on the microstructures and magnetic field-induced strains (MFIS) of the alloy. The results showed that the MFIS value increases when ellipse-shaped pores elongate along the twin boundary, and the effects of porosity and pore size on MFIS for porous Ni-Mn-Ga alloys were explored.

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.

Summary: In this work, a physics-constrained neural network is used to predict grain-level responses in FCC material by incorporating crystal plasticity theory. 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.
