“…Earlier reports also suggest that the usage of lubrication may reduce the amount of shear band by 32.3% more than the non-lubricated one [22], which may significantly improve the deep drawing performance of the steel plate. If the non-lubricated surface is removed by 1/4th of thickness, the r-value can be increased by 0.3 [25].…”

Interstitial free (IF) steel is widely used in the automotive industry, due to its excellent deep drawing performance. In this study, in order to study the influence of different rolling processes on the texture evolution and deep drawing performance of IF steel, we conducted rolling experiments on IF steel with different temperatures, different reduction rates, and different lubrication conditions. The impact of texture on the deep drawing performance of the steel was also analyzed. The microscopic and macroscopic texture analyses were performed using electron backscatter diffraction (EBSD) and X-ray diffraction (XRD), respectively. Deep drawing performance was analyzed by measuring the r-value. The results showed that in non-lubricated rolling, the r-value increased with the decrease in the reduction rate, and the r-value increased with the increase in the deformation temperature. The maximum value of r is 0.85. But in the case of lubricated rolling, the r-value increased significantly from 0.74 to 1.47 compared to non-lubricated (keeping the reduction rate and the rolling temperature constant). The lubrication reduced the shear deformation of the steel surface, resulting in a γ texture on the surface. Texture uniformity along the thickness direction resulted in an increase in the r-value of the steel.

“…The key requirement to selection of material for engineering structures is high structural strength, which is understood as material resistance to loads acting during operation of the facilities (static, impact, cyclic), including those in conditions of negative temperatures and corrosive environment. Impact strength evaluates quality of metal (cold brittleness) and reflects processes causing its behavior in different loading conditions, while standard static mechanical properties of metal in the state of cold brittleness remain unchanged [1][2][3][4][5]. To obtain required set of physical and mechanical properties of engineering structures, a composite material based on a highstrength steel can be used with a structure formed as alternating layers of ferrite and perlite.…”

In this work, the fracture surface of a 1.0481 steel sample having a layered ferrite-martensitic structure after special heat treatment was studied by optical and scanning electron microscopy. The samples were subjected to a shock-bending test at negative temperature. A sample made of the same steel with a homogeneous martensitic structure was used for comparative analysis. The features of the destruction mechanisms of the studied samples are described. Keywords: construction steel, layered structure, fracture surface, visco-brittle mechanism, impact strength.
