An Overview of Dual-Phase Steels: Advances in Microstructure-Oriented Processing and Micromechanically Guided Design
Cemal Cem Tasan,Martin Diehl,Dingshun Yan,Marion Bechtold,Franz Roters,Lars Schemmann,Chengwu Zheng,N. Peranio,Dirk Ponge,Motomichi Koyama,Kaneaki Tsuzaki,Dierk Raabe +11 more
TL;DR: In this article, the authors provide a detailed account of these improvements, focusing specifically on microstructure evolution during processing, and expander expansion during the fabrication of dual-phase alloys.
Journal ArticleDOI
Hydrogen-assisted decohesion and localized plasticity in dual-phase steel
Motomichi Koyama,Motomichi Koyama,Cemal Cem Tasan,Eiji Akiyama,Kaneaki Tsuzaki,Kaneaki Tsuzaki,Dierk Raabe +6 more
TL;DR: In this article, a high-resolution scanning electron microscopy-based damage quantification technique has been employed to identify strain regimes where damage nucleation and damage growth take place, both with and without hydrogen precharging.
Journal ArticleDOI
Effect of hydrogen on the fracture behavior of high strength steel during slow strain rate test
TL;DR: In this paper, the effect of hydrogen on the fracture behavior of quenched and tempered AISI 4135 steel at 1450 MPa was investigated by means of slow strain rate tests on smooth and circumferentially-notched round-bar specimens.
Journal ArticleDOI
Inverse Temperature Dependence of Toughness in an Ultrafine Grain-Structure Steel
TL;DR: An inverse temperature dependence of toughness in an ultrahigh-strength bcc steel with an ultrafine elongated ferrite grain structure that was processed by a thermomechanical treatment without the addition of a large amount of an alloying element is observed.
Journal ArticleDOI
Bone-like crack resistance in hierarchical metastable nanolaminate steels
Motomichi Koyama,Zhao Zhang,Meimei Wang,Meimei Wang,Dirk Ponge,Dierk Raabe,Kaneaki Tsuzaki,Hiroshi Noguchi,Cemal Cem Tasan +8 more
TL;DR: It is shown here that when steel microstructures are hierarchical and laminated, similar to the substructure of bone, superior crack resistance can be realized and the exceptional properties enabled by this strategy provide guidance for all fatigue-resistant alloy design efforts.
