Insitu investigation of tensile deformation behaviour of cold-rolled interstitial-free high-strength steel in scanning electron microscope

Experimental investigation of early strain heterogeneities and localizations in polycrystalline α-Fe during monotonic loading

“…In addition, most slip marks are also visible as they produce a small out-of-plane step on the surface. Therefore, the heterogeneous plastic deformation of the microstructure was accompanied by noticeable out-of-plane motion, which meets the results presented in the literature [3,56,57]. Besides, strain localizations measured with dic do not necessarily correspond to areas with high || ∇Z|| and inversely.…”

“…They arise from the interactions between the elastically and plastically anisotropic crystals [1]. Understanding the development of these heterogeneities is of paramount importance when the lifetime of a component strongly depends on its microstructural features [2,3]. The build-up of these heterogeneities and the occurrence of plastic localization is not yet fully understood in polycrystals, let alone in ferrite.…”

Optimal Control of Inclusions to Prevent “Sand-Hole” Surface Defects in Deep Cold-Drawn Battery Cups for Electrical Vehicles

“…As it known, inclusions can easily cause such problems in steel because of different deformability, hardness, thermal expansion and so on. [21][22][23][24][25] Moreover, it is accepted that inclusions smaller than 10 μm seldom cause problems in steel. As a result, it was inferred that these scattered Al 2 O 3 particles probably originated from a crushed Al 2 O 3 cluster.…”
