Ductile and scalable 3 GPa steel via a hierarchical microstructural architecture [PDF]
Nature CommunicationsUltrahigh-strength steels with yield strengths exceeding 3 GPa and appreciable ductility represent a transformative frontier in materials science. Conventional strengthening approaches, such as cold-work hardening, however, inevitably trade strength for ...

Torsional rigidity of steel square tubes with elastic anisotropy
Nihon Kikai Gakkai ronbunshu, 2016 Elastic moduli of metal sheets have planar anisotropy determined by crystalline texture. Texture control is effective in raising Young's modulus of steel sheets in some directions on the plane.

High Strain Rate Properties of High Strength Steel Sheets
International Journal of Automotive Engineering, 2011 High strain rate properties of sheet steel largely depend on its strength level and strengthening mechanisms. The strain rate sensitivity of flow stress has a close relation with the hardness of a softer phase, which indicates superior strain rate ...
