“…The strength of the connection is proved. Researchers at Hebei University of Science and Technology carried out basic research on the rapid shear connection technology of endless rolling intermediate blanks, and designed the dynamic and static connection mechanism [15,16], which is a relatively simple six-bar and one-slide mechanism, and derived the motion function. Optimization of this mechanism is employed using a genetic algorithm (GA) and the optimization parameters of this mechanism are obtained; the kinematics analysis show that the connection time is less than 0.1 s and the connection thickness is more than 80% of the thickness of the solid-state metal.…”

The high-temperature deformation behavior of Q345 steel is detected by a Gleeble-3800 thermal simulator. The Arrhenius constitutive equation for high-temperature flow stress and the dynamic recrystallization model are constructed. With the secondary development technology, customized modifications are made on existing Deform-3D software. The constructed constitutive model and dynamic recrystallization model are embedded into Deform-3D to realize the secondary development of Deform-3D. The grain size and volume percentage distribution of dynamic recrystallization are obtained by simulating the shear connection process at high temperature and high speed. The results show that the constitutive equation and the dynamic recrystallization model constructed in this paper can be used to predict the evolution of the microstructure. The difference between the prediction results and the experimental data is about 3%. The accuracy of Arrhenius constitutive equation, dynamic recrystallization model and the feasibility of software secondary development are verified.

The static shear extrusion bonding experiment was carried out on the Q345 plates by the solid-state metal joining device with fast shearing. Meanwhile, based on the experimental and theoretical analysis, the influence of shear rate, the press quantity on the interface formation and microstructures evolution mechanism during shear extrusion bonding process were analyzed, and mechanical properties was investigated. The results show that with the increase of the press quantity, the interface formation divides into three stages, and the grain refinement is improved through dynamic recrystallization. The deformation work is provided by the bonding device, which is affected by shear rate. When the press quantity reaches 125%, the tensile strength of the specimens with high shear rate and low rate are 499.56MPa and 500.56MPa, respectively.
