Abstract: The presented paper shows the way of determination of the thermo-chemical reserve zone location in the working space of blast furnace, using data from the horizontal probe. Reserve zone is the bottom boundary of the preparatory zone, and so the area of indirect reduction of iron oxides. [..] Read more

Abstract: Acicular ferrite has been used to increase the toughness and strength of low-carbon alloy steel weld metals. Finely dispersed nonmetallic inclusions can serve as nucleation sites for acicular ferrite, and thus reduce the grain size and consequently improve the mechanical properties of steel. [..] Read more

Abstract: The bell-less blast furnace tops of the type Wurth or Vitkovice, i.e. the bell-less tops equipped with a rotary chute, enable effective management of the blast furnace burdening. [..] Read more

Abstract: In the paper the results of the theoretical and experimental study of behaviour of mischmetal and non-ferrous metals in steels will be presented. The samples of two special steels were prepared with micro-alloying of mischmetal by application of plasma metallurgy. [..] Read more

Abstract: In this research we studied the evolution of the microstructure of the two wires used in the manufacture of electric energy transportation. The first wire is an aluminum alloy of A 6101 type (or AGS) and the other is a pure copper (Cu-Ducab 98.33 %). [..] Read more

Abstract: Phase composition of the studied high-alloy martensitic steel has been analyzed by metallographic methods, plastometric tests and thermodynamic calculations performed in the Thermo-Calc Software. Basic parameters of the formability and deformation resistance were determined depending on the forming temperature (800 - 1250 °C) and strain rate (0.1 - 17 s-1). [..] Read more

Abstract: High-grade medium-carbon steel C45 with content of carbon 0.42 – 0.50 % and manganese 0.50 – 0.80 %, intended for hardening and tempering, has been often used for production of die forgings and the less exposed machine components. The hot stress-strain curves of this steel were investigated by uniaxial compression tests using the Hot Deformation Simulator HDS-20 within a wide strain range (up to 1.0). [..] Read more

Abstract: The influence of shrinkage caused by austenitic transformation on thermal fatigue of mill rolls made of four different cast steels was investigated. The samples were collected from the work surface perpendicularly (or close to it) to the axis of the rolls. [..] Read more

Abstract: In recent years, the dual amorphous phased bulk metallic glass (DAPBMGs) was studied with interest by researchers of materials science, which is a new class of bulk metallic glasses (BMGs). These materials consist of several amorphous phases and are expecting to bring together all the favorable properties for each phase. The DAPBMGs with soft magnetic properties can be obtained by powder metallurgy process; the amorphous powders can be produced either by mechanical alloying (MA) or by high pressure Ar gas atomization.

In addition, it used in estimation a possibility of equipment for producing new gages of steel strip. We used the invariable method to designing the pattern of rolling, which based in automatical computer-assistant engineering. [..] Read more

Abstract: This paper presents the results of plastometric modelling of the Zr-Nb-Sn zirconium alloy blank forging process. The results were obtained by performing a test on the “Gleeble 3800” plastometric simulator in hot conditions.. [..] Read more

Abstract: The problem of plate hot rolling on mill 5000 JSC "Severstal" was solved by finite element modeling in Deform-3D. It was shown by Deform-3D calculations that the presence of cold surface layers greatly increases the strain rate in the central layers of the plate thickness, which can greatly improve the quality of metal.
