This paper investigates the surface texture evolution after a short phase transformation annealing in low vacuum on ultra low carbon steel sheets alloyed with high Mn and Al and the cold rolled steel sheets of industrial composition alloyed with silicon. The ultra low carbon steel sheets with high Mn and Al show surface monolayer which has a characteristic surface texture components <100>//ND texture and microstructure with special grain morphology. Contrastingly, the industrial composition alloyed with silicon does not show specific surface texture components inspired by surface energy anisotropy at the surface. The composition depth profiling investigations performed on the all steel sheet surface shows that oxidation characteristics of alloying elements at the metal vapour interface have played a decisive influence on surface texture evolution. Further, transformation annealing in higher vacuum reveals that surface texture can be obtained in an industrial composition alloyed with silicon.

In this item, the low carbon steel hot sheets by compact strip production (CSP) technology were cold rolled and annealed in laboratory. texture evolution during the production process of CSP-cold rolled strip were investigated by means of the XRD. The results were as follows: After hot deformation of thin slab formed a strong γ- fibre orientation texture, the density of texture increase with the cold rolled reduction increased, especially for the negative texture {100}, in γ-fibre orientation cold rolling texture density has no significant change. Compared to the traditional process, hot rolled steel sheet has higher texture, cold-rolled steel sheet has the same texture, and after-annealing sheet has further higher texture in the CSP-cold rolling process. This study enables better understanding and control on the evolution of textures the cold-rolled steel sheet processed by CSP technique and provides theory support for exploiting the CSP the cold-rolling deep drawing steel sheet

The present study examines deformation textures in low-carbon steel with microstructural heterogeneity. EBSD and XRD have been used in order to follow the evolution of the texture in relation with deformation evolution. The non-deformed material shows a {111} fibre texture (γ-fibre), with a main component {111} <112>. The deformation aptitude may be related for bcc metals to the evolution of this fibre texture component. To follow the evolution of the deformation textures, tensile tests were performed from 5% up to failure. During deformation, the {111} <110> deformation component sharpens. In the presence of this component in the non-deformed sheet, plastic flow is easy, while the grain reorientation from the initial orientation {111} <112> towards the bcc deformation orientation {111}<110> implies an important micro-constraint state, which is able to initiate cracking in the studied sheet during drawing. Heterogeneous structure that develops during deformation induces heterogeneous mechanical behaviour; noted this evolution is not predictable using global characterization techniques. The morphological analysis shows the micro-band presence. In a heterogeneous structure the risk of cracking seems to increase in the presence of small grains {111} <112 > clusters. The EBSD technique showed the adjustment of the grain orientation from the component {111} <112> towards the global deformation orientation {111} <110>. This process can explain the possibility of crack propagation in a globally ductile material characterized by a main component {111} <110>.

The evolution of the microstructure, macrotexture, microtexture and mesotexture has been studied during the annealing at 760°C after temper rolling (9% thickness reduction) of a non-oriented electrical steel sheet containing 2 wt. % Si. Results showed that the coarse grained microstructure, obtained on annealing, is produced through a recrystallization mechanism that advances from the surface to the interior of the sheet. However, starting of this process is delayed due to the presence of Si. The majority of experiments carried out in this work have been repeated for a low-carbon steel (C = 0.0385; Mn = 0.18%) containing only 0.03% Si and the results obtained were practically identical to those observed in the steel containing 2% Si. The main difference observed between both steels was that the process of formation of the exaggeratedly large grains was slower in the steel containing 2% Si.
