Abstract: Energy analyses in the metallurgical sector traditionally focus on upstream processes such as steelmaking and refining. However, when energy consumption is evaluated at the level of individual products, downstream manufacturing stages can represent a significant share of the total energy demand. [..] Read more

Abstract: Shear cutting operations, such as blanking, are critical in forming technology but often oversimplified in FE simulations, reducing predictive accuracy for cut edge quality. This study evaluates three failure modelling approaches for a FE model of DC04: the modified porous Gurson model and the Johnson-Cook model with element deletion and mesh separation. [..] Read more

Abstract: Based on the prior experience of IPB Polska Sp. z o.o. [..] Read more

Abstract: This study investigates wall thickness variations during the multi-stage deep drawing of bearing housings under industrial-experimental conditions. The paper outlines a methodology for evaluating both material formability and wall thickness distribution within the drawn components. [..] Read more

Abstract: The production of metallic sheet composites (layered, multi-material structures) by rolling is a manufacturing route that enables the integration of complementary material properties within a single product. This poster investigates the rollability of different composite architectures, with emphasis on how the layer arrangement, material pairing, rolling schedule (pass design), and process parameters influence final product quality.

Abstract: This paper presents an analysis of the potential for automation of the hot die forging process, considering the types of forging units used and the feed and material handling strategies. The research is based on our own experience and R&D work related to the implementation, design, and testing of robotic cells for the production of die forgings, including high-volume production (≥0.5 million forgings per year).

Abstract: The Cu-graphene composite combines the high electrical and thermal conductivity of copper with the extreme strength and stiffness of graphene. This composite is thus stronger, more wear-resistant and at the same time highly conductive. [..] Read more

Abstract: Prior information of physical and mechanical properties of materials is very crucial in design and development of a mechanical system. In the normal course, sufficient data is available at around room temperature. [..] Read more

Abstract: ASTM A694 F65 is a low-alloy steel valued for its high yield strength, good weldability, and excellent toughness at low temperatures. Owing to its balanced strength and impact resistance, it is extensively employed in the production of flanges and fittings for low-temperature, high-pressure service, where tensile strength and corrosion resistance are not the primary design requirements.

Abstract: Most practical users of optical microscopy think in terms of magnification and resolution. Magnification refers to the ratio of the distances between two points in the sample and to those in its image. [..] Read more

Abstract: Additive manufacturing (3D printing) represents a modern method of material production in many industrial sectors. Materials produced in this way can also be used in the field of hydrogen storage and transportation. [..] Read more

Abstract: This study examines the microstructure, phase composition, and mechanical properties of a lightweight Fe-Mn-Al-C steel alloy containing Cr, Si, and Cu that was processed through electroslag remelting. The alloy was synthesized through induction melting, followed by electroslag remelting. [..] Read more

Abstract: The long-term global trend in energy consumption indicates that the gradual shutdown of nuclear power units after reaching their planned service life may increase the risk of power outages. One effective way to mitigate this risk is to extend the operation of nuclear units beyond their originally designed lifetime. [..] Read more

Abstract: Niobium is a widely used microalloying element in the production of HSLA steels; however, supply-related and cost-related risks justify the investigation of alternative solutions. The aim of this study was to determine whether the complete or partial replacement of niobium with titanium is feasible in EN 10149-2:2013 grade S355MC steel while maintaining the mechanical properties required by the standard. [..] Read more

Abstract: Long-term operation of steam pipelines in power plants, due to high temperatures and pressures, leads to gradual material degradation and changes in mechanical properties. Therefore, it is necessary to apply appropriate diagnostic methods to assess the current condition of the material and estimate the residual service life of the pipeline. This paper focuses on the application of the Small Punch Test (SPT) method to monitor changes in material properties of steam pipelines during periodic inspections. [..] Read more

Abstract: One of the approaches to simulate creep testing conditions as close as possible to the real service conditions of boiler tubes is the use of internal pressure creep tests (burst tests). This paper describes the implementation and results of such creep tests performed on welded joints of superheater tubes ø 44 × 6.3 mm made of HR3C steel, welded by the TIG process using a filler material based on the nickel superalloy Inconel 617. [..] Read more

Abstract: The sensitivity of the Koistinen-Marburger (KM) model parameters governing the martensitic transformation kinetics in SAE 9254 spring steel was systematically investigated using a finite element approach. A transient thermal model was developed in ANSYS Workbench to simulate the quenching of cylindrical specimens under two industrially relevant cooling protocols: single-step cooling at 40 °C/s) and two-step cooling (20 °C/s followed by 1 °C/s), where the slower second stage was designed to promote bainite formation prior to the martensitic transformation.

Abstract: Hydrogen is considered one of the primary energy carriers of the future due to the growing demand for clean and renewable energy. Consequently, its global consumption is expected to increase significantly, as indicated by available forecasts. [..] Read more

Abstract: A special group of paint systems is paint coatings for military applications, mainly for camouflaging weapon systems and military equipment. Paint coatings are fundamental to camouflage - they conceal vehicles/objects in the optical range, both in visible light (VIS) and near-infrared (NIR). [..] Read more

Abstract: This paper examined the suitability of thermally sprayed coatings for high-temperature corrosion protection. The coatings' resistance to abrasive wear and erosion, which, along with corrosion, are inherently damaging factors in power boilers, particularly fluidized bed boilers, was also determined.
