Journal ArticleDOI
Orientation gradients and geometrically necessary dislocations in ultrafine grained dual-phase steels studied by 2D and 3D EBSD
TL;DR: In this article, orientation gradients and geometrically necessary dislocations (GNDs) in two ultrafine grained dual-phase steels with different martensite particle size and volume fraction were analyzed using high-resolution electron backscatter diffraction (EBSD).
Journal ArticleDOI
Deformation and fracture mechanisms in fine- and ultrafine-grained ferrite/martensite dual-phase steels and the effect of aging
TL;DR: In this paper, three ferrite/martensite dual-phase steels varying in the ferrite grain size (12.4, 2.4 and 1.2μm) but with the same martensite content (∼30 vol%) were produced by large-strain warm deformation at different deformation temperatures, followed by intercritical annealing.
Journal ArticleDOI
Experimental and numerical study on geometrically necessary dislocations and non-homogeneous mechanical properties of the ferrite phase in dual phase steels

TL;DR: In this paper, it was shown that the properties of the ferrite phase change with distance from the martensite grains, leading to the idea that local hardening is caused by geometrically necessary dislocations.
Journal ArticleDOI
Effect of grain refinement to 1 μm on strength and toughness of dual-phase steels
TL;DR: In this article, a large strain warm deformation at different temperatures and subsequent intercritical annealing has been applied to obtain fine grained (2.4m) and ultrafine-grained (1.2m) ferrite/martensite dual-phase (DP) steels.
Journal ArticleDOI
On the Effect of Manganese on Grain Size Stability and Hardenability in Ultrafine-Grained Ferrite/Martensite Dual-Phase Steels
TL;DR: In this article, the influence of the Mn content on microstructure evolution is studied by scanning electron microscopy (SEM) and high-resolution electron backscatter diffraction (EBSD) combined with energy dispersive X-ray spectroscopy (EDX).
