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.

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). [..]

Abstract:
Among the steel and cast steel resistant to corrosion most modern and dynamically developing group areferritic-austenitic alloys, commonly known as duplex. Higher than austenitic steels, mechanical properties and good corrosion resistance in both overall and pitting make duplex steels irreplaceable material in thepetrochemical industry, power, pulp and paper, food.

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. [..]

Abstract:
High strength and ductility of the TRIP (Transformation Induced Plasticity) steels is attributed to the transformation induced plasticity effect resulting from the strain induced martensitic transformation of the retained austenite in the multiphase (ferrite, bainite) microstructure. The precise characterisation of the multiple microstructure of low alloyed TRIP steels is of great importance for interpretation and optimalization of their mechanical properties. [..]

Abstract:
The paper deals with the study on creep behavior and minor phase evolution in two types of heterogeneous weld joints of P23 and P91 steels during long-term creep exposure at 550 °C. The filler material in Weld A corresponded to P91 steel and the filler metal in Weld B was similar to the chemical composition of P23 steel. [..]

Abstract:
Carburization, followed by quenching and tempering, is commonly used process to increase hardness and wear resistance of low carbon steels. Such process, besides improving mechanical properties and performance of steel surface, may cause however undesirable side effects such as: increased residual stress in surface layer, distortion of heat treated element or even initiation of cracking.

Abstract:
It is possible to successfully propose the physical-metallurgical and structural conditions for the equilibrium between steel strength and toughness by designing structural parameters which have a positive effect on the relation between local and macroscopic fracture processes. In carbon steels and microalloyed steels for a wide range of technical uses, whose structure after heat treatment consists of a basic matrix of tempered lower bainite with precipitated carbides and sometimes other types of inclusions, toughness is dependent primarily on the size distribution of second phase particles, their volume ratio, and also the strength of the matrix/particle phase boundary and the mechanical properties of structural phases.

Abstract:
Dynamic tensile testing of structural materials is becoming more and more important due to the need to obtain relevant data for components design mostly with the use of FEM in many industries such as automotive and power industries. The difference of the material behaviour under dynamic loading and quasi-static loading is that the dynamic strength or yield stress usually increases as the strain-rate increases. [..]

Abstract:
In the past, V-ROL N steel, produced at Poldi Kladno, was used for many years for a manufacture of aircraft undercarriages, particularly for quite famous small aircraft L 410. As a result of privatisation process in the nineties and other circumstances, the V-ROL N steel, known by its very good or even excellent properties, has not been more available. [..]
