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. [..]

Abstract:
Nanocrystalline stainless steels exhibit limited thermal stability due to their high-volume fraction of grain boundaries, making them susceptible to grain growth at elevated temperatures. Enhancing thermal stability is therefore essential to broaden their potential structural applications. [..]

Abstract:
This study presents the results of fatigue investigations performed on additively manufactured austenitic stainless steel 316L produced using the Laser Powder Bed Fusion (LPBF) technique. Fatigue tests were conducted under axial tension–compression loading for three different stress ratios: R = −1, −0.5, and 0. [..]

Abstract:
The influence of specimen temperature on displacement efficiency was investigated for duplex stainless steel EN 1.4462 using a 20 kHz ultrasonic fatigue testing system. Resonance-controlled tests were conducted over incremental excitation levels defined by the function generator output voltage (VPP), with continuous phase control to maintain stable resonance. [..]

Abstract:
Metallographic images mapping metal surfaces, including their chemical composition, were obtained with sizes up to 1 Gpix (2×3 mm2) and a digital pixel size of 75 nm, well below the theoretical limit of the optical microscope. These images are part of a global priority discovery (Large-Area Digital Optical Microscopy - LADOM). [..]

Abstract:
Long-term operation of nuclear power plants requires reliable monitoring of material degradation while minimizing the amount of material removed from components for the assessment of their current condition, residual lifetime, and structural integrity. Monitoring of changes in key material properties should include all degradation mechanisms occurring during operation, with thermal ageing being one of the main factors affecting these properties.

Abstract:
This work focuses on the development and characterization of functionally graded materials (FGM) produced by combining the nickel-based superalloy MoNiCr and the austenitic stainless steel 316L using the DED LB/W additive manufacturing technology. The aim was to verify the technological feasibility of multi-material printing of two metallurgically distinct alloys, evaluate the quality of the interface between them, and assess the influence of deposition order and subsequent heat treatment on the resulting microstructure and hardness distribution.
The results show that the deposition order significantly affects the nature of the transition zone. [..]

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:
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. [..]

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.

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:
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. [..]

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.

Abstract:
The work reviews phase evolution, mechanical, electrical, thermal and tribological properties of NbMoTaW100-z(CN)z coatings deposited using reactive DC magnetron co-sputtering. The concentrations of the metals were not equimolar, therefore, the resulting material was attributed to the compositionally complex compounds instead of high-entropy stabilized ceramics. [..]
