Summary: In this study, the body-centered-cubic (BCC) Fe81Ga19 alloy was produced using twin-roll strip casting technology. The secondary recrystallization of Goss grains was achieved through warm rolling and heat treatment. Deformation twinning was observed in the warm-rolled sheets and was found to be related to grain orientation. Additionally, deformation twinning can adjust grain orientation and activate dislocation slip, providing the possibility for producing sheets using rolling technology.

Summary: In this study, three-dimensional finite element modeling and cellular automaton-finite element model were used to analyze and simulate the twin-roll strip casting and top side-pouring twin-roll casting processes. By comparing the two processes, it was found that the top side-pouring twin-roll casting achieved more uniform temperature distribution and intense stirring in the micro-melt pool, resulting in a high-quality thin strip. The simulation results were in good agreement with the experimental results, confirming the feasibility and accuracy of the simulation.

Summary: High-performance borated steels containing 2.40 wt% B were fabricated through a designing combination of titanium-alloying along with twin-roll strip casting technology. The addition of titanium facilitated the formation of dispersive and fine M2B borides by acting as heterogeneous nucleation cores for borides, leading to an excellent total elongation of 16.2% in the steels. The relationship between microstructure and mechanical properties of the steels were clarified, with ductility determined by the volume fraction of α-Fe matrix and strength dominated by the volume fraction of borides.

Summary: The study investigates the effects of nucleation and growth of recrystallized grains at different annealing temperatures on the microstructure and texture evolution of annealed sheet. The magnetic and mechanical properties of the final sheets were also analyzed. The results indicate that the shear band in the cold-rolled sheet promotes the formation of {100} texture, regardless of annealing temperature. Combining low-temperature nucleation and subsequent high-temperature growth is more beneficial for the formation of strong {100} texture and has higher preparation efficiency. Moderate nucleation and preferential growth are important for the formation of strong beneficial texture. Combined with aging treatment, the low-temperature nucleation sheet achieves an excellent match between mechanical and magnetic properties.

Summary: In this study, the solidification process in strip casting was investigated by inserting a thermocouple into the strip during casting. The results showed that secondary cooling was necessary to rapidly solidify the inside of the strip, and the cooling rate and supercooling degree were influenced by the Si content and viscosity.

Summary: This study investigates the microstructural evolution and mechanical properties of Mg-3Al-1Bi alloys produced by twin-roll casting and hot rolling, and compares them with AZ31 alloy. The addition of Bi in twin-roll cast alloys reduces central segregation and introduces thermally stable Mg3Bi2 phases. These phases lead to particle stimulated nucleation and dynamic recrystallization, resulting in grain refinement and uniform microstructure in the alloys. However, these brittle phases also act as cracking sources and degrade elongation.

Summary: The effect of Mn content on the microstructure evolution and recrystallization behavior of AA6061 twin roll casting plate was investigated. It was found that Mn element can significantly change the recrystallization behavior and induce particle induced recrystallization (PSN) effect. The mechanical properties, including strength and elongation, of the plate were optimized at Mn content of 0.46%.

Summary: Research on the cold working properties of high-silicon iron alloys was conducted, with attempts to suppress the formation of superlattice structures through different cooling strategies. Results showed that the cooling strategies were not sufficient to prevent the formation of superlattice structures, which hindered cold processing.

Summary: The mechanical properties and product specifications of bimetallic clad strip are closely related to the mechanical behavior of the bonding interface. By analyzing the effects of cast-rolling velocity on the interface temperature, pressure, and thickness, it is found that lower cast-rolling velocity can lead to better interface bonding and higher bonding strength.

Summary: The study aims to investigate the deformation mechanisms involved in Twin-roll Thin Strip Casting Process for high-permeability 6.5 wt.% Si electrical strip. Using crystal plasticity theory and VPSC model, the activation of single and multi-slip systems during deformation is analyzed to understand the evolution of crystallographic orientations. The proposed CP-based method serves as a reference for studying deformation behavior in other semi-solid forming processes.

Summary: An oriented Fe-6.5 wt%Si alloy with excellent magnetic properties was successfully prepared using twin-roll strip casting. The abnormal Sigma 3 grain boundaries in the as-cast strip were studied. The experimental results showed that the Sigma 3 grain boundary in the alloy had good thermal stability and could refine the microstructure by inhibiting growth of structure in the as-cast strip. It also improved the toughness of the matrix and restrained crack propagation, which was beneficial for plastic working. Moreover, the low migration rate of the Sigma 3 grain boundary stabilized the matrix and helped achieve abnormal growth of Goss grains.
