Crystallographic texture control in a non-oriented electrical steel by plastic deformation and recrystallization

Texture and anisotropy are persistent characteristics of polycrystal. Because of the ordered and periodic arrangement of atoms in crystal lattices, responses of each oriented crystals in a polycrystal to the same external forces are not similar. Crystal grains which are better accommodated to boundary conditions because of their energetically...

Use of the Correlation between Grain Size and Crystallographic Orientation in Crystal Plasticity Simulations: Application to AISI 420 Stainless Steel

Crystal plasticity models attempt to reproduce the complex deformation processes of polycrystalline metals based on a virtual representation of the real microstructure. When choosing this representation, a compromise must be made between level of detail at the local level and statistical significance of the aggregate properties, also taking into...

From micro-mechanisms of damage initiation to constitutive mechanical behavior of bainitic multiphase steels

Global warming, continuous demand on energy from fossil fuels as a limited natural resource, and costumers’ high expectations regarding product quality are three global challenges that the automotive industry is facing. Fuel consumption reduction has a significant impact on preserving fossil fuels, lowering fossil fuel dependency and the CO2...
