Summary: This study explores the feasibility of improving the mechanical properties of explosive welded clad plates through subsequent hot-rolling and reveals that increasing the thickness reduction per pass or decreasing the rolling temperature can enhance tensile properties. Microstructure characterization shows that the significant improvement in ductility is closely related to the reduction of accumulated strain in the alloy sheets and the elimination of interface delamination formed during explosive welding.

Summary: This study aims to analyze the influence of rolling process on the microstructure and corrosion properties of Mg/Al bimetallic bars obtained by explosive welding method. Two types of rolling, classical rolling (Variant I) and modified rolling (Variant II), were conducted at different temperatures (300 degrees C and 400 degrees C). The results showed that the material after rolling exhibited lower values of both icor and current in the passive range. Intermetallic phases Al3Mg2 and Mg17Al12 were observed in the joint zone of Mg/Al rods rolled at 400 degrees C, with a columnar and coarser grain structure.

Summary: CP-Ti/304 stainless steel bimetallic sheets were prepared without Ti-Fe intermetallics by using laser-MIG arc welding. The joint exhibited a maximum tensile strength of approximately 680 MPa, fracturing at the laser weld zone and the right side of MIG arc weld zone. Liquid mixing of dissimilar metals was avoided in the process, preventing the formation of Ti-Fe intermetallics.

Summary: This study proposed a dynamic self-constrained explosive welding method to fabricate a copper-steel bimetallic tube without using an external mold. The mechanical balance of the self-constrained process was analyzed through 3D numerical simulations. The results showed that the dynamic self-constrained system effectively balanced the stress, velocity, and displacement between the inner and outer tubes, reducing the maximum hoop tensile stress and modifying the welding interface.

Summary: In this paper, the microstructure and properties of a Ti/Mg alloy clad plate manufactured by explosive welding were studied. The results showed that the bonding interface of the clad plate was made up of straight areas and wavy areas, with element diffusion occurring in straight areas and a melting zone occurring in wavy areas. The clad plate exhibited improved tensile strength, shear strength, microhardness, and corrosion resistance compared to the original sheets.

Summary: Understanding the fracture mechanism from the source is crucial for fusion welding of high strength SiCp/Al composites. In this study, the fracture characteristics and related damage mechanisms near the fracture crack tip in a notorious SiCp/2A14Al joint were investigated using FIB, TEM, and EBSD techniques. The results revealed that the weld fusion region of Ti-SiCp/2A14Al joint consisted of a fine equiaxed crystal region and a SiC accumulation region. The two regions exhibited different degrees of geometric dislocation density evolution after 0.25% tensile strain, with higher dislocation density observed in the elastic deformation stage due to SiC aggregation. This provides a new insight into fracture research of high strength SiCp/Al composites.

Summary: We report the formation of an unusual texture on the sheet-surface of a rolled Mg-3Al-0.4Mn alloy, where a typical basal texture is formed at the center of the sheet and an unusual texture with vertical tiling is observed at the sheet-surface. The surface promotes prismatic slips and dynamic recrystallization, leading to a high fraction of fine basal-textured grains and a small fraction of off-basal-textured grains. In contrast, the center preserves a relatively high fraction of deformed grains, promoting the growth of basal-textured grains and the formation of the typical basal texture.

Summary: This research compared the high-cycle fatigue (HCF) performances of Ti-6Al-4V titanium alloy joints with a thickness of 30 mm, welded using vacuum electron beam welding (EBW) and laser welding with filler wire (LWFW). The fatigue strength of the LWFW joint was found to be only 65% that of the EBW joint. Analysis revealed that a larger microhardness gradient in the LWFW joint was the main reason for this difference, with the average microhardness of the weld metal (WM) in the LWFW joint being 41 HV lower than that of the base metal (BM). The presence of punctate beta phases in the WM of the LWFW joint could be an important factor contributing to its softening. These research findings provide data supporting the application of EBW and LWFW of Ti alloy in aviation manufacturing.

Summary: This study investigated the bonding strength between intensive high-strength martensitic stainless steel powder and different substrates through an intensive additive repair experiment using laser coaxial powder feeding cladding technology. The results showed that the bonding strength of the repaired interface was influenced by the distance and orientation relationship between the composition points of the filling material and the substrate, and the tensile strength and elongation of the repair parts decreased as the distance and orientation relationship increased.

Summary: In this study, a high entropy alloy was introduced as an interlayer into laser beam welded joint of Ti-22Al-27Nb to analyze its impact on the evolution of microstructure and joint performance. It was found that the addition of the high entropy alloy triggered heterogenous nucleation during solidification, resulting in a fine-grained microstructure with a greater proportion of high angle grain boundaries. The joint prepared with the high entropy alloy showed an improvement in hardness and ultimate tensile strength, as well as a ductile mode of failure during tensile testing.

Summary: The research aimed to improve the mechanical performance of fusion welding of molybdenum alloys. Pre-heating, titanium microalloying, and brazing were used to regulate defects, microstructures, and mechanical performance. The addition of titanium helped in solid-solution strengthening, purifying grain boundaries, and inhibiting pore defects, while brazing enlarged the bonding area and shifted the stress concentration point. The joint strength was improved from 140.8 MPa to 399.8 MPa, and the fracture mode changed from intergranular fracture to transgranular cleavage-like fracture.

Summary: Through experiments, it was found that scanning rate and powder heat absorption rate have a significant impact on the dilution rate in the laser cladding repair process. The dilution rate mainly affects the softening degree in the heat-affected zone and the hardness in the fusion zone, with high dilution rates potentially leading to cracking of the fusion zone.
