The process involves depositing a molten metal onto a substrate, which solidifies rapidly to form a clad layer. In this study, the effect of the DED-cladded material of SS316 on a Duplex SS was investigated using Barkhausen noise (BN) analyzer, and the BN signals was measured before and after the cladding process. The method is demonstrated to be effective in detecting microstructural changes, identifying defects, and evaluating the residual stress of the cladded material. The peak and RMS values of both cases exhibit an upward trend when the magnetizing frequency and magnetic field intensity are increased. There is a lower BN response appeared in the duplex SS compared to the cladded material, which gave direct information of the smaller grain size present in the duplex SS. The hysteresis loop characteristics, namely the average permeability, and remanence, showed an inverse relationship with respect to the low-frequency range. However, coercivity is directly proportional to all frequency ranges of the magnetizing waveform, whether it is a sine or triangular wave. The coercivity of the cladded material showed higher than the duplex SS, which is due to having a lower hardness level in the cladded material. Also, a parametric simulation is done to analyze the temperature distribution and heat affected zone (HAZ) at the interface of the deposited material and substrate. The results showed that at the higher value of the laser power, more HAZ appeared; however, as increasing the scanning speed, the HAZ values showed less at the constant value of laser power. The study provides valuable insights into the magnetic properties of cladded materials and their substrates, which can be used to evaluate material quality, hardness, and other mechanical properties.","PeriodicalId":764,"journal":{"name":"Russian Journal of Nondestructive Testing","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2024-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141165688","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper utilizes experimental and numerical methods to explore the relationship between nonlinear coefficients derived from frequency-domain analysis results and crack damages in composite materials. Additionally, it analyzes the time-domain responses of three excitation signals along asymmetric paths under various damage scenarios, revealing distinctive characteristics of damaged materials. Furthermore, it investigates cross-correlation coefficients between different target damages and the damage-free case in the same path direction. Numerical results demonstrate a correlation between the extent of damage and the cross-correlation coefficient. The study also highlights that different excitation signals exhibit varying sensitivities to different damage types. Lastly, a damage index is proposed to quantify the interaction between the propagation path and damage, enabling a more accurate characterization of material damage. This study serves as a valuable complement to existing material damage characterization methods.","PeriodicalId":764,"journal":{"name":"Russian Journal of Nondestructive Testing","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2024-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140563957","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Then, how reliable can it be? In this sense, the objective of the research has been to estimate the reliability of dye penetrant inspection to detect discontinuities in relation to their size. Six experimental tests were performed by three inspectors, with visible and fluorescent dye penetrants, on twenty welded joints of similar surface characteristics, containing 63 typical weld discontinuities arranged according to shape and size, whereas POD reliability quantitative estimates were developed by the hit-or-miss statistical method. For the test system, the fluorescent penetrants, due to their greater sensitivity compared to the visible ones, registered greater reliability in revealing smaller discontinuities. The POD estimators were a50 (1.469 mm < 1.978 mm), a90 (6.348 mm < 7.474 mm), a90/95 (14.58 mm < 15.77 mm). Fluorescent dyes allowed a higher rate and probability of detection; both factors showed a tendency to increase as the discontinuities size increased.","PeriodicalId":764,"journal":{"name":"Russian Journal of Nondestructive Testing","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2024-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140563975","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The pore distribution was obtained using a combination of mercury intrusion porosimetry (MIP) and nuclear magnetic resonance (NMR) techniques. The influence of calcium carbonate content, density, confining pressure, and shear strain on the pores was studied. Introducing pore classification to assess the extent of the damage under different conditions and the relationship between different types of pores. The results show that the content of added calcium carbonate has little effect on pore distribution when the density is low (1.4 and 1.5 g/cm3). The content of calcium carbonate has an influence on pore distribution when the density is high (1.6 g/cm3). With the density increases, the number of macropores and mesopores between soil particles decreases, while the small pores increase. The confining pressure results in the preferential drainage of free water from macropores. The porosity decreases as the confining pressure increases. Under the same confining pressure, as the shear strain increases, the large pores decrease while the small pores increase. Based on the analysis of damage degree, the shear strain is positively linearly related to the damage degree of intragranular mesopores, which forms a convex function relationship with intragranular macropores and intergranular mesopores (except under a confining pressure of 100 kPa).","PeriodicalId":764,"journal":{"name":"Russian Journal of Nondestructive Testing","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2024-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140563937","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
