“…Some researchers believe that an intermetallic layer with a thickness of less than 10 lm impose no detrimental effect on the joint strength and even may improve the joint quality. However, when the layer thickness is more than 10 lm, the joint strength declines significantly [11,[13][14][15][16][17][18]. It is noteworthy that some investigations revealed that the formation of intermetallic phases, regardless of their thicknesses, reduces the bond quality of the joint [19,20].…”

“…In order to restrict large differential material flow, due to strength mismatch in the component blanks, two different blank holder forces are used in the process [15]. The blank holder was modeled as a segmented tool and a higher value of constant force of 144 kN was applied for DC06 and a constant force of 72 kN was applied for DP600 steel.…”

Tailor-welded blanks have strength and thickness mismatch leading to non-uniform deformation imposing complex stress states in the formed part. In this study, numerical simulations are performed to determine the stress states and their influence on the springback behavior of deep-drawn tailor-welded blanks. The tailor-welded blank models consisting of different steels were simulated and the springback is evaluated using split ring test. The results provide an insight on the material combination and weld region location on the springback of TWB´s. The tailor-welded blanks subjected to same forming conditions may result in different springback behavior, depending on the material combination and the blanks orientation. The springback also depends on the section geometry and location of the splitting region in the formed part. Increasing section modulus significantly reduces the springback behavior in a blank.

“…Compared to other welding methods, laser welding can create a narrow fusion zone (FZ) and heat-affected zone (HAZ), and has become a widely used welding method of TWBs in the modern automobile industry [2,3]. However, the performance of laser TWBs is greatly reduced due to the existence of welded joints, which limits their application in automobiles [4][5][6][7][8]. Farabi [9] researched the tensile properties of laser TWBs of DP600 steel and the results showed that the hardness increased significantly in the FZ, the yield strength increased and the ultimate tensile strength remained almost unchanged after welding.…”

Abstract:The influence of magnetic treatment on the yield strength, the ultimate tensile strength and the elongation of laser tailor welded blanks (TWBs) of DP600 steel was investigated by uniaxial tensile tests. The experimental results showed that the yield strength and the ultimate tensile strength of the TWBs had only a slight change, but the elongation increased by 13.90%-36.23% after the magnetic treatment. The dislocation distributions in the fusion zone (FZ) and the heat-affected zone (HAZ) were observed respectively by transmission electron microscopy (TEM). It was found that after magnetic treatment, the dislocations in both the FZ and the HAZ of the TWBs increased and showed a relatively uniform distribution. The mechanism of the mechanical property improvement of the TWBs by the magnetic treatment was then revealed on the basis of the relationship model between the dislocation and shear strain, considering the evolution of magnetic domains and Frank-Read dislocation multiplication in a magnetic field.
