In the study, effects of welding parameters on microstructure and mechanical properties electrical resistance spot welded TBF/DP600 steel sheets 1.2 mm thickness were investigated. TBF used in study was both with without electro-galvanized. Microhardness measurements tensile shear tests taken as basis determining properties, while optical microscope for microstructural characterization. The nug...

Friction stir welding (FSW) is a solid-state joining method that suitable for dissimilar materials such as aluminum and steel due to its comparatively low process temperatures. Such hybrid joints are of great interest in view lightweight construction efforts various industrial sectors transportation. As the combination different metals structures may cause corrosion problems area because format...

Abstract. A series of samples from four automotive materials AKDQ, HSLA50, DP600, and AA6022-T43 were deformed in a channel draw processes with different levels of draw bead penetration. As a result, varying magnitudes of deformations in plane strain mode and residual stresses were obtained. Through-thickness stress profiles were obtained non-destructively using a novel, high resolution X-ray d...

This work established strain-based forming limit diagrams (FLDs) for DP600 steel sheets by means of experimental investigation and theoretical prediction. The results showed that compared to the curve (FLC), predicted Keeler equation, FLCs Hill’79 yield criterion, or Logan-Hosford were more suitable predicting sheets. Solutions from analytical methods FLD, based on combining uniaxial tensile te...
