Summary: The crystallographic character of shear band and its influence on recrystallization texture in strip-cast electrical steel were studied. It was found that shear band played an effective role in adjusting local lattice rotation to accommodate heavy deformation, and the crystallographic direction of shear bands was related to the recrystallization texture and magnetic properties.

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: 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: An improved dip test apparatus was used to simulate strip casting of 6.5 wt pct Si steel, showing that the high cooling rate resulted in a strip with low iron loss and the magnetic permeability and iron loss varied with increasing heat treatment temperature. The as-cast strip mainly consisted of large columnar grains, with only small particles of MnS-TiN found, and after annealing, a large number of small particles such as TiN precipitated from the ferrite matrix. The magnetic permeability and iron loss of the silicon steel strip produced by strip casting are comparable to those of silicon steel products produced by other techniques.

Summary: Using finite element software ProCAST, the study predicted the temperature and flow fields, turbulent kinetic energy, and melt-pool outlet temperature in the top side-pouring twin-roll casting (TSTRC) process for 6.5 wt.% Si steel. The research investigated the impact of different process conditions on TSTRC and determined an appropriate processing technique for producing 6.5 wt.% Si steel, while also evaluating the influence of violent stirring in the melt-pool on microstructure formation. The results showed that vigorous stirring in the melt-pool was beneficial for forming an equiaxed crystal structure, achieving near-final shapes for both the metal sheet and microstructure. The chosen process demonstrated good consistency with experimental results.

Summary: The addition of yttrium (Y) affects the microstructure, texture, and magnetic properties of cold-rolled 6.5 wt% Si steel sheets. Adding an appropriate amount of Y can optimize the recrystallization texture, increase magnetic induction strength, and reduce core loss. Excessive Y content deteriorates the magnetic properties by increasing inclusions and gamma-fiber oriented grain nucleation.

Summary: This study aims to improve the plasticity of strip casting non-oriented 6.5%Si electrical steel through chemical modification. The results showed that the addition of Ce during strip casting promoted heterogeneous nucleation and refined the solidification microstructure, while not affecting the ordering condition of the as-cast strip. Increasing the tensile temperature improved grain-boundary cohesion and prevented intergranular cracking, eventually enhancing the tensile ductility through dynamic recovery and recrystallization. The rare-earth treatment is considered an effective method for increasing the ductility of strip casting non-oriented 6.5%Si electrical steel.

Summary: The effect of pre-annealing on the recrystallized texture of hot-rolled Fe-1.6 wt% Si non-oriented electrical steel was investigated. It was found that pre-annealing treatments caused the texture to change from a near-random distribution to {116} < 151 > texture and near-{001} < 140 > texture. The grain size remained almost unchanged, with an average size of 125 μm in the normalized bands. Furthermore, the pre-annealing process improved the magnetic properties of the material.

Summary: This study investigates the effects of Re and Ta interactions on the precipitation of the TCP phase in experimental alloys under long-term thermal exposure. The study finds that microstructure segregation is not fully eliminated even with standard heat treatment, and the interaction between Re and Ta enhances the formation of the TCP phase. Thermodynamic calculations and first-principles analysis reveal that Re significantly improves the driving force of TCP phase precipitation. The study also observes a phase transition from the sigma-phase to the P-phase, with Ni playing a crucial role in the diffusion process.

Summary: The microstructures and corrosion resistance of TC11 components were significantly improved using a high-power, high-speed laser metal deposition (LMD) process and subsequent post-heat treatment, with greater improvements observed in the deposition direction. The significant improvement of corrosion resistance in the deposition direction is mainly due to the weakening of the charged galvanic corrosion effect between the non-interlayer zone and interlayer zone.

Summary: In this study, the microstructures and mechanical properties of interphase precipitation strengthening micro-alloyed steels were investigated. The addition of Cr was found to increase the yield strength without significant decrease of ductility. Thermodynamics analysis revealed that the addition of Cr led to grain refinement and decrease of sheet spacing of nanoprecipitates. Calculations showed that the decrease of interphase-precipitated carbides sheet spacing and the refinement of grain size were responsible for the strength enhancement of Cr microalloyed steel.

Summary: In this study, bioinspired web-liked multiphase composites were successfully constructed using boron-modified polysilazane polymer. The composites consisted of long TiB nanowires as 'web' and hybrid TiC and Ti3Si particles as 'nodes'. The enhanced strength of these composites was attributed to the synergistic load transfer of the hybrid reinforcements. This study provides a promising design approach for developing high-performance composites with high reinforcement content, utilizing polymer instead of traditional ceramic powder.
