“…18 Tensile-test specimens of monolithic martensitic steel and multilayer steel containing a martensitic steel layer. 21) specific strength and ductility may be possible if light metals are inserted as a layer component along with ductile steels. Also, if a high-impurity recycled steel is employed as a brittle but high-strength layer, more environmentally friendly highperformance steel may be possible with reduced energy consumption and CO 2 emission in steel making.…”

Multilayer steels have been developed to provide a novel route to achieving higher-performance steels by employing a high-strength steel and a high-ductility steel independently in the layer structure. In this article, a background to the development, design, fabrication, properties, and applications of multilayer steels are overviewed. Multilayer steels exhibit improved combinations of strength and ductility compared with existing monolithic steels and also excellent deformation behaviors under high-strain-rate deformation as well as good formability. Those improved performances of multilayer steel are achieved by increased interfacial toughness between the layers and decreased thickness of the brittle steel layers according to the fracture toughness of the brittle steel and the strength of the ductile steel. The concept of multilayer steels is extended by applying different combinations of components, such as Mg-steel multilayer composite.

“…To improve this situation, we have employed a multilayered steel composite, in which lath martensite can be uniformly elongated under uniaxial tension to a strain of over 50% by selecting an appropriate layer thickness and mechanical properties of each component. 13,14) This enhanced elongation enabled us to conduct detailed studies to clarify the unknown deformation behavior of lath martensite at larger strain levels, [15][16][17][18][19] and a number of findings regarding the local deformation behavior were obtained.…”

“…1) Multi-layered materials that combine austenitic steels with high ductility and martensitic steels with high strength possess a good balance of high strength and ductility, as well as the good formability compared to the low ductility martensitic steel. [2][3][4] Recently, the uniform elongation of asquenched martensitic steel was increased from 6% to more than 50% level by the multi-layered structure design through bonding the martensitic steel sheets with the austenitic steel sheets, 4) which enhances the expectation to fabricate highstrength structural materials.…”

A multi-layered composite material composed of alternating SUS301 and SUS420J2 steels, prepared by hot-rolling bonding, shows a superior strength and ductility balance than the components. Few researches have been addressed on texture features of structural multi-layered materials during cold-rolling. In the present work, cold-rolling with three reductions (20%, 40% and 65%) in thickness was conducted on both the two monolithic steels (SUS301 and SUS420J2) and the multi-layered material consisting of SUS301 and SUS420J2 components. Texture and microstructure development during the cold-rolling deformation in both the monolithic steels and multi-layered material were investigated by using EBSD technique. It was found that austenite phase in SUS301 component of the multi-layered material showed weaker h110i==ND texture as compared to the monolithic SUS301 steel although the similar texture characteristics appeared in both conditions. On the other hand, the martensite phase in SUS420J2 component of the multi-layered material showed stronger f112gh110i texture components than the h111i==ND and h100i==ND texture components that were dominant in the monolithic SUS420J2 steel. It is considered that the constraint condition and shear stress at component layer interfaces are significant for the formation of Brass component observed as the final stable orientation of austenite phase of the SUS301 steel in the multi-layered samples, and the formation of the f112gh110i texture of martensite phase of the SUS420J2 steel in the multi-layered samples during the cold-rolling deformation.
