Abstract. The microstructure and microhardness distribution in surface of low carbon Hardox 450 steel coated with alloyed powder wires of different chemical compositions are studied. It is shown that the microhardness of 6-8 mm thickness surfaced layer exceeds that of base metal by more than 2 times. The increased mechanical properties of surfaced layer are caused by the submicro and nanoscale dispersed martensite, containing the niobium carbides Nb2C, NbC and iron borides Fe2B. In the bulk plates a dislocation substructure of the net-like type with scalar dislocation density of 1011 cm-2 is observed. The layer surfaced with the wire containing B possesses the highest hardness. The possible mechanisms of niobium and boron carbides formation in surfacing are discussed.

“…The resulting microstructure consists of M7C3 carbides and Austenite [1]. Chromium carbides may be deposited by various welding processes, but submerged arc is the welding process most commonly used due to its operational simpilicity and productivity [2]. There are, however, a number of problems associated with weldiing that make decrease the designed properties.…”

Welded deposited chromium carbide overlay's has been widely used in various branches of welding overlay's industry related to wear. Characterization techniques are an important tool in the development of chromium carbide overlays resistant to wear, enabling the identification of phases, constituents and defects. In this work one used optical microscopy, scanning electron microscopy and energy dispersive spectroscopy on chromium carbide overlay's deposited by submerged arc welding process. The characterization techniques identified precisely the elements of the overlay's enabling point of the main cause of the observed defects such as cracks, porosity and clusters of particles known in the industry as " rice crispy" .

“…For larger defects or for the thicker layer, the use of the efficient method with the solid or cored wires will be more effective. Regeneration has to recreate the features of the used element, and it should occur in a commercially reasonable manner [2][3][4][5]10,16,18,20,21,28].…”

In the paper, the regeneration process of the material in grade C45 using the MAG welding was analysed. The effect of preheating on the properties of the regenerated layers was determined. Preheating technology was used to facilitate the process of regeneration and minimize the risk of imperfections. The use of numerical methods allows one to observe the direction of changes in the properties, structures and emerging stresses and accompanying strains of the elements depending on the temperature applied for preheating.Modeling of the stress state in the element made of medium carbon steel during the regeneration process was performed on original software based on the finite element method. The implemented numerical model consists of three basic elements -thermal phenomena, mechanical phenomena and phase transformations in the solid state. The performed numerical analysis made determining the optimum heating conditions possible, so that the material in the area of joint didn't show tendency to create structural notches associated with the stress state.
