In particular, dual-energy transformation algorithms can be applied to search for minerals hidden in waste rock. The method is most effective when the conditions for capturing X-ray images and energy levels are chosen correctly. This study compares the effectiveness of image processing using the dual-energy method in three cases of spectrum composition modification: first, by adjusting the voltage on the X-ray tube; second, by attenuating low-energy radiation using a copper filter; and third, by combining these methods. Fragments of beryl embedded in crushed muscovite were used as detection samples. A pulsed X-ray source that generates nanosecond-duration radiation pulses was used in this study. An original high-voltage generator circuit was implemented for the method of controlling radiation energy by varying the peak voltage on the X-ray tube. The use of such X-ray sources allows for obtaining high-resolution X-ray images of moving objects.","PeriodicalId":764,"journal":{"name":"Russian Journal of Nondestructive Testing","volume":"60 9","pages":"1040 - 1050"},"PeriodicalIF":0.9,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142811253","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}

To solve the problems, in this paper a correction method is proposed for digital radiography (DR) imaging with linear array detectors based on fan-shaped X-ray beams. Firstly, the dynamic scaling method is employed to eliminate numerical bias of the linear regression fitting, thereby correcting the abnormal projection data. This method effectively reduces vertical bright line interference in imaging results and improves the quality of DR images. Secondly, to address the issue of position diffusion in DR images, the arcdegree adaptive compression (ADAC) algorithm is used to determine the optimal imaging area, adaptively correct the position relationship between the detection array and the DR image pixels, and reconstruct images proportionate to the size of the object under test. The experimental results indicate that the method proposed in this paper can effectively remove the abnormal values caused by DH boards splicing and generate DR images consistent with the original object scale, providing an effective data correction and image reconstruction method for imaging with linear array detectors based on fan-shaped X-ray beams.","PeriodicalId":764,"journal":{"name":"Russian Journal of Nondestructive Testing","volume":"60 9","pages":"1062 - 1071"},"PeriodicalIF":0.9,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142811254","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 article employs nonlinear acoustic methods to assess the response of CFRP plates, including unwoven, twill weave, and plain weave structures, to surface microcrack damage. A set of air-coupled nonlinear ultrasonic automatic detection systems was designed to acquire the amplitudes of the fundamental frequency and the second harmonic in the received signal, enabling the calculation of relative nonlinear parameters. Furthermore, the nonlinear cumulative effect was verified by varying the propagation distance. The experimental results highlight the significant influence of woven fabric on the outcomes of nonlinear acoustic testing. Specifically, the nonlinear response of unwoven CFRP to microcracks is the most pronounced, followed by twill weave CFRP plates. Notably, plain weave CFRP can significantly hinder the effectiveness of nonlinear acoustic detection. In cases where CFRP plates are loaded with such woven fabric, there is a potential for lower relative nonlinear parameters when damaged compared to their healthy state.","PeriodicalId":764,"journal":{"name":"Russian Journal of Nondestructive Testing","volume":"60 9","pages":"976 - 988"},"PeriodicalIF":0.9,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142810979","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}

A secondary extraction algorithm is designed based on the normal direction according to the commonly used laser stripe center line extraction algorithm. The algorithm improves the Gaussian curve fitting method. By combining the fine state refinement method, Hessian matrix method, Gaussian curve fitting and light plane calibration, the fast extraction of the center line of the laser stripe is completed, and the mapping relationship between the two-dimensional coordinates of the points on the laser center line and the three-dimensional coordinates in the camera coordinate system is obtained.

If the pipe diameter is greater than a hundred wavelengths, the DAF can be utilized for reflector imaging, considering multiple reflections from boundaries while assuming that the test object is flat. The errors in forming the DAF image of reflectors will be minimal in this case. However, if the pipe diameter is several tens of wavelengths and the wall thickness is approximately half the pipe diameter, then to obtain a quality DAF image of the reflectors, the geometry of the test object must be taken into account. This paper examines the features of image formation when recording echo signals with an antenna array or matrix while scanning both the outer and inner surfaces of the test object. Numerical and model experiments demonstrate that to achieve high-quality DAF images of reflectors when scanning the outer surface of a thick-walled pipe with a small diameter, both an antenna array and an antenna matrix can be used. This is due to the presence of the physical focusing effect of the ultrasonic field. However, when scanning the inner surface of a thick-walled pipe with a small diameter, echo signals must be recorded using an antenna matrix to reconstruct the image of the reflectors due to the defocusing effect.","PeriodicalId":764,"journal":{"name":"Russian Journal of Nondestructive Testing","volume":"60 9","pages":"965 - 975"},"PeriodicalIF":0.9,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142810982","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}

Comprehensive nondestructive testing techniques (NDT) are vital for the successful quality evaluation of critical components in this domain. Appropriate selection of the NDT scheme is essential for the qualification of such components. Major NDT techniques are designed based on the interaction of electromagnetic radiation and the response of the sound or heat energy transmission or reflection from the test object. The common defects noticed in the components made through additive manufacturing (AM) routes are pores, clusters of porosities, micro-cracks, lack of fusion and layer delamination. Considering the morphology and the complications in the geometry of aerospace components, many conventional NDT techniques are unsuitable for the inspection of AM components. Detection of unfused powder in the AM components by conventional radiography is difficult due to the low radiation attenuation coefficient gradient between the unfused and fused metallic regions. Also, the detection of defects in the radiography technique depends entirely on the beam path. Multiple radiography images with different beam angles and film combinations are essential to get the maximum information on the defects by conventional radiography techniques. In this aspect, computed tomography, a noncontact NDT technique provides a better solution for determining embedded defects such as lack of fusion and layer separation due to presence of unfused powder in the AM components. The present study compares the capability of computed tomography and 2D digital radiography for the identification of lack of fusion defects in stainless steel SS316L specimens fabricated through the Laser powder bed fusion AM route.","PeriodicalId":764,"journal":{"name":"Russian Journal of Nondestructive Testing","volume":"60 8","pages":"955 - 964"},"PeriodicalIF":0.9,"publicationDate":"2024-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142672473","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}
