3. Material properties Uni-axial tension tests were performed for the DP590 base sheet (with 2 mm thickness) to measure hardening, yield strength and R-values along 0°, 45°, 90° off the rolling direction. The strain-rate sensitivity was also measured using the high speed tension tests....
Table 1 Mechanical properties of the rivet Full size table 2.1.2Materials and Experimental Setup The self-piercing riveting test connecting materials of base plates are, respectively, DP590 and AA6061. The mechanical properties of these materials are listed in Table2. In this study, the dissimilar...

(BH) steel, but the trend of lightweight car body drives steels to have higher strength for outer panel use. 490MPa grade DP steel is beginning to be applied into some automobiles, and 590MPa grade DP steel is a good candidate for the future outer panel material. In this study, several...
DP steel properties Low yield-to-tensile strength ratio provides excellent ductility for superior cold forming with high ultimate tensile strengths. High strain hardening and bake hardening further increase tensile strength. Excellent deep drawing and high stretching properties. ...
The welding technology of high strength steel (DP590) for vehicle was studied, and the research on the microstructure and properties of high strength steel with different welding parameters were analyzed. The main results include the weld surface morphology, weld cross section, micro-hardness, ...
