Abstract: There is a persisting trend in automotive industry to increase safety of passengers while decreasing the cost and fuel consumption of the car. Usage of ultra and advanced high strength steels for manufacturing of car body parts is a way, how to achieve this goal. [..] Read more

Abstract: The paper presents a comparative study of zinc coatings tribological properties in dry friction conditions in the context of assessing coating wear intensity. For this purpose, three zinc coatings were analyzed: hot-dip, galvanic and lamellar, put to steel bolts made of 23MnB4 steel normally applied in the automotive industry. [..] Read more

Abstract: PTA surfacing is widely used technology of increasing lifespan and wear resistant characteristics of machine components. There is a wide range of alloys which can be used as filler material; however, plasma cladding of High Speed Steel (HSS) is not yet frequently used. [..] Read more

Abstract: Plasma sprayed alumina coatings find numerous applications in various fields, where they enhance the properties of the base material. Examples include thermal barriers, wear resistance, electrical insulation, and diffusion and corrosion barriers. [..] Read more

Abstract: This paper presents the research focused on surface defects of galvannealed car body sheets. The fragments of a car bonnet panel after press forming as well as steel sheet used for its production in as-delivered condition (prior to press forming) were investigated. [..] Read more

Abstract: The influence of surface preparation of steel 41Cr4 on the structure and corrosion resistance of the zinc coating has been presented in the paper. The aim of the study was to determine the method of surface preparation fittings for overhead power lines made of steel 41Cr4 guaranteed to obtain zinc coating of a required thickness and high corrosion resistance.

Abstract: Titanium alloys and their weld joints find wide application, in particular in aircraft, automotive and chemical industries, because of their outstanding specific strength and corrosion resistance. The high reactivity of these alloys and the strong degradation effect of elements contained in the atmosphere (H, N and O) make it necessary for these alloys to be welded in protective atmospheres or in vacuum.

Abstract: Solidification process plays an important role in the production of metallic materials. Conditions of this process considerably determine mechanical properties of semi-finished products. [..] Read more

Abstract: The influence of Inconel 718 particles on the mechanical and physical properties of magnesium has been investigated in this study. Magnesium samples with 0.7, 1.4 and 2.4 vol.% of Inconel particles were prepared using disintegrated melt deposition technique followed by hot extrusion.The microstructures of the extruded composites were examined by light and electron microscopy.

Abstract: A2B type Ti-Ni hydrogen storage alloy, which has also dissolved Zr in it, was synthesized directly from TiO2-ZrO2-NiO mixture in the molten CaCl2 electrolyte by the electro-deoxidation method at 900 C. Sintering of the oxide mixture at 1100 C for 2 h did not cause formation of any mixed type Ti-Zr-Ni oxide. [..] Read more

Abstract: High entropy alloy AlCoCrFeNiTi0.5 was produced by a combination of mechanical alloying (MA) and spark plasma sintering (SPS) processes. In our study we have investigated the effect of four different sintering temperatures (ranging from 1150 to 1300 ºC) on microstructures and phase composition of sintered samples by means of X-ray diffraction (XRD), scanning electron microscopy (SEM) and Vickers microhardness tests.

Abstract: The beta-titanium alloys are used for bioapplications (e.g. orthopaedic or dental implants) due to their excellent properties like biocompatibility, corrosion resistance, high strength, low Young’s modulus). [..] Read more

Abstract: A comprehensive meshless numerical model was developed for the simulation of direct chill casting under the influence of low frequency electromagnetic field. The model uses mass, momentum and energy conservation equations to simulate the solidification of aluminum alloy billets. [..] Read more

Abstract: Since the discovery, metallic glasses (MS) and bulk metallic glasses (BMG - metallic glasses with a minimum diameter of 1 mm) have opened up a novel engineering field in the world of metallic materials. These types of glassy metals with good glass forming ability have excellent mechanical, magnetic and corrosion resistance properties, that are dissimilar to properties of conventional crystalline materials.

Abstract: The as-cast Fe2NiAl samples were treated in accordance with the following regime: water quenching from 1240 °C (after holding for 20 min); cooling from 1240 °C (after holding for 20 min) at a critical cooling rate up to an intermediate temperature Tq = 900 – 20 °С with subsequent water quenching. Detailed studies of the solid solution decomposition, microstructure and magnetic properties of the samples are reported. [..] Read more
