Abstract:
In the steel industry, requirements for production optimization by the help of decreasing of energy and economical demands are increasing at the production of alloyed steels in the EAF. During the treatment of alloyed steel charging in the EAF containing chromium, its loss by oxidation and by the transition into slag happens. [..]

Abstract:
Outdated machine for continuous casting of steel (CCM) has often fail to meet the requirements for production of the desired high quality carbon or stainless steel blank. Their control system acts as a so-called Black Box System, which provides operators the possibility of the system as needed to adjust and tune in order to achieve the required quality of steel produced.

Abstract:
Plane strain and uniaxial compression tests are generally used for characterization of a material constitutive behavior during hot forming. Interpretation of the results obtained by such tests is complicated by flow inhomogeneity occurring in a specimen volume and temperature variations. [..]

Abstract:
The effect of Thermomechanical Processing, using cold deformation with the combination of post deformation annealing and induction hardening based on the of dislocation structure inheritance effect on the strength, ductility, and torsion static strength has been studied. The metal with an initial structure of lamellar pearlite has shown to be more advantageous with respect to the strengthening intensity during cold rolling and the combination of mechanical properties after the TMP.

Abstract:
An integral computer model/program for simulation of steels hot rolling on mill 2000 of SEVERSTAL was developed. The model provides for the following calculations: · temperature distribution over the cross section of a rolled strip at any location along its length; · rolling forces and torques;austenite microstructure evolution under hot rolling taking into account grain growth, dynamic/static recrystallization and strain induced carbonitrides precipitation; · austenite transformation during accelerated strip cooling at the run-out table accounting for formation of polygonal ferrite, pearlite, bainite of different morphology, and martensite; · mechanical properties of rolled strips (yield stress, ultimate tensile stress and relative elongation).

Abstract:
The paper presents results of numerical simulation of the asymmetric rolling process for band with shape ratio h0/D = 0.072 – steel grade S355J2G3. The study was conducted to determine the differences in the impact factor of different kinds of asymmetry on the band bending after leaving the deformation zone and the power parameters of rolling process.

Abstract:
The influence of intensive plastic deformation on compacted Al powders was evaluated. The samples subjected to deformation processing were prepared from powder particles with diameters between 25 and 45 μm, pre-compacted using double-step cold isostatic pressing (CIP) at 200+300 MPa applied for 30 seconds each and subsequently vacuum sintered at 500°C for 60 min.
