Effect of microstructure on the fracture response of advanced high strength steels
… conditions. The grades were an uncoated DP780, a high yield DP780, a galvanized DP780, a TRIP780, a galvannealed DP980, a galvanized DP980, an uncoated DP980, and a fine grained DP980. All AHSS grades were tensile tested to obtain values for ultimate tensile strength, yield strength, …

Spot Friction Welding of Ultra High-Strength Automotive Sheet Steel
… manufacturing. Alloys studied included DP780, DP780EG, DP980, and DF140T sheet steel of varying thickness from 1.2 mm to 1.4 mm. Welding was accomplished using a PCBN standard tool. Weld strengths were then compared to a proposed AWS standard. Initial hardness readings were taken in …

Effects of deformation modes on the susceptibility of delayed fracture of advanced high strength steels
… types of commercially-produced sheet steels (DP780, DP980, TRIP780 and TRIP980). Specimens were strained by either uniaxial tension or bending prior to hydrogen charging and their delayed fracture response was compared with non-deformed samples. Micro hardness testing was performed to assess …

Edge fracture of AHSS sheets under out-of-plane loading followed by in-plane loading
… on edge fracture of a commercially available DP780 steel sheet. The study reveals that it is the substantial plastic deformation introduced during the out-of-plane sheet blanking process that compromises the material ductility within the Shear Affected Zone (SAZ), and subsequently causes the …

Edge Fracture Prediction Of Dual Phase Steels With Consideration Of Microstructures
… of edge fracture of two AHSS, Dual Phase DP780 and DP980. The HE test includes two processing steps: hole punching and hole expanding. The punching process creates holes of various sheared edge morphologies, which are the input to the hole expanding process, along with the intrinsic …

Comportamiento en frío y en caliente de aceros con bajo contenido de carbono obtenidos a través de procesos de laminación controlada
… de tracción de dos aceros de fase dual (DP600 y DP780), así como la caracterización microestructural para poder entender el efecto de este tipo de laminación controlada en la creación de la microestructura responsable de las propiedades mecánicas exhibidas por estos aceros. Los aceros HSLA con …
