1.2GPa Advanced High Strength Steel with High Formability
SAE Technical Paper Series, 2014<div class="section abstract"><div class="htmlview paragraph">To reduce the Body in White (BIW) mass, it is necessary to expand the application of Advanced High-Strength Steels (AHSS) to complex shaped parts. In order to apply AHSS to complex shaped parts with thinner gauge, high formability steel is required.

Shear Fracture of Advanced High Strength Steels
Journal of Iron and Steel Research International, 2014Failure experiments were carried out through a stretch-bending test system for advanced high strength steels, i. e. dual-phase (DP) steels and martensitic steels (MS). The die radius in this system was designed from 1 to 15 mm to investigate the failure mode under different geometries. Two failure modes were observed during the experiments. As a result,

On twist springback in advanced high-strength steels
Materials & Design, 2011The sheet metal components made of advanced high-strength steel (AHSS) become fairly attractive in reducing weight and enhancing operational performance of products. However the corresponding forming process often generates more severe springback. This paper aims to investigate the behavior of twist springback in advanced high strength sheet components,

Passivation Layers of Ultra-Advanced High Strength Steels and High Strength Steels
The fundamental ambition of this thesis is to assess the effects of chemical com-position, temperature and elapsed time reaction on scale formation. The control of oxidation rates and oxide morphology are focal points of interest along with the evolution and formation mechanisms of scale morphology with time and temperature.openaire +2 more sources
