Summary: Coatings play a crucial role in preventing corrosion on ships or marine structures, with thickness impacting their effectiveness. Ultrasonic NDT is a convenient method for measuring underwater coating thickness, but the high energy attenuation and absorption rates in offshore coatings present challenges. Despite these difficulties, accurately measuring the thickness using ultrasonic methods has proven effective and versatile for various objects in water environments.

Summary: Assessment of the technical condition of large-panel buildings, especially after thermomodernization works, is difficult due to uncertainty in non-destructive tests and limited use of destructive tests. Access to vulnerable joints connecting precast elements is challenging. However, demolition of such buildings presents a unique opportunity for comprehensive testing and comparison of results obtained through different methods. This allows for scaling of non-destructive testing methods and identification of typical relationships. Therefore, large-scale demolition sampling is of great importance for evaluating the technical condition of prefabricated buildings.

Summary: This article discusses the sustainability and environmental friendliness of pipe belt conveyors, and introduces the use of microwires as sensing elements for mechanical load diagnostics. The study finds that the thickness of the glass coating significantly affects the lifetime of the microwires, while the length of the microwires has negligible influence on the number of bending cycles until damage occurs.

Summary: A novel non-destructive testing (NDT) method for detecting defects in carbon fiber-reinforced polymers (CFRPs) at low frequencies is proposed. This method uses eddy current loss to characterize the thermal power of the eddy current in CFRP and a new probe to detect the eddy current loss and inspect CFRP. Experimental results demonstrate that the developed method can provide appropriate detection results and successfully detect fiber direction up to a frequency of 750 kHz.

Summary: Damages in structures are inevitable and it is important to have effective damage detection techniques. Many engineering applications use composite materials, and common damages include delamination, fiber breakage, and fiber pull-out. Various non-destructive testing techniques have been reported for damage detection in composites, but traditional techniques are difficult to implement due to the complex properties of the materials. This study explores the use of artificial neural networks for analyzing NDT data for damage detection and discusses the pros and cons of different methods.

Summary: This article focuses on non-destructive testing methods for aircraft parts, mainly using ultrasonic and eddy current techniques for defect detection, and combining the advantages of these two methods through machine learning. A simulated training database with US and EC signals in an aluminum block was implemented for training artificial neural networks (ANNs) to characterize flaws. Experimental results show the effectiveness of the method in defect detection, depth estimation, and radius estimation.

Summary: The magnetic flux leakage (MFL) method is commonly used to detect discontinuity in ferromagnetic materials. This study aims to determine the optimal sensor position for the MFL method and examine the effects of crack geometry and magnetization velocity on the MFL signal. ANSYS Maxwell simulation software is used to design and produce a pipeline inspection gauge (PIG) device with the optimal magnetization velocity, sensor position, and sensor selection. Experimental investigations were carried out at different velocity values to study the velocity-dependent variation of the MFL signal.

Summary: Fiber-Reinforced Polymer (FRP) bars/strands are a promising alternative to steel reinforcements in concrete due to their corrosion resistance, lighter weight, higher strength, and better durability. However, there is limited research on non-destructive testing (NDT) methods for detecting damage in FRP bars or embedded FRP reinforcements. This paper investigates the effectiveness of Ground Penetrating Radar (GPR) and Phased Array Ultrasonic (PAU) in detecting FRP bars/strands. The results show that GPR can detect GFRP bars/strands and CFRP strands, while PAU can only detect GFRP and CFRP strands.

Summary: This study investigates the sensitivity of the Barkhausen noise technique against strain-induced martensite in AISI 321 austenitic stainless steel. The results show that Barkhausen noise emission increases with plastic straining, driven by the martensite fraction in the deformed matrix. Additionally, the uniaxial tensile stressing induces stress and magnetic anisotropy in the samples.

Summary: Mullite, a versatile material, was synthesized from natural kaolin alone or in a composite with alumina. The effect of calcination on kaolinite was studied, which led to dehydration and amorphization of its phase composition. The thermal properties of dehydrated and untreated kaolinite-based materials were found to be similar.

Summary: Tensile test specimens of an age-hardened CuCr1Zr alloy were subjected to direct electrical current heating at 800 degrees C in a Gleeble thermal-mechanical simulator. Mechanical properties were monitored using Vickers hardness test, while changes in grain structure were examined with light metallography. TEM was used for quantitative analysis of fine precipitates during annealing, showing a gradient grain structure with recrystallized structure after annealing at 800 degrees C. Coarsening kinetics of chromium precipitates during overaging followed Lifshitz, Sloyzov, and Wagner's theory.

Summary: The plastic instabilities of a silicon iron single crystal were studied using spherical nanoindentation coupled with acoustic emission detection. Three possible scenarios were identified, including gradual plasticity development, sudden onset of plasticity, and an elastic response. Reversible microstructural changes were also observed, expanding the definition of acoustic emission. Furthermore, acoustic emissions proved to be a powerful method for examining different deformation mechanisms observed during indentation loading.

Summary: The application of a DC current enables fast Ag+ -> Na+ ion exchange in SLS glass. The effects of processing parameters, electric current, and treating time on both air and tin sides of SLS float glass are studied, revealing non-Fickian diffusion. The ion exchange kinetics are similar on both sides, but the structure/microstructure is vastly different. Clear silver nanoclustering occurs on the tin side, resulting in metallic particles near the surface. The formation of nanoparticles involves a deep structural reorganization.
