In the present work, a study has been conducted to see the effect of solid particle erosion on Ti–6Al–4V alloy fabricated by direct metal laser sintering. The fabricated sample was characterized using optical microscopy and scanning electron microscopy. It was observed that a long martensitic phase structure (in the form of α/α' laths) was retained since the heat treatment temperature was far below the β transus value. Using the Taguchi experimental approach, the SPE tests were conducted for different impact angles, velocities, and temperatures. This approach optimized the number of experiments for measuring the erosion rate and predicted the most influencing variable in the test. The scanning electron microscopy technique was also used to characterize the eroded sample. The effect of impact velocity dominated the erosion behaviour of Ti–6Al–4V alloy, followed by temperature and impact angle. At highest temperature of 650 K, erosion rate decreased with an increase in impact angle and increased with an increase in impact velocity. This study aims to identify the optimal parameter combination to minimize the erosion rate.</p>","PeriodicalId":764,"journal":{"name":"Russian Journal of Nondestructive Testing","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2024-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142212935","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}

These cracks have the potential to permit the ingress of chlorides, leading to corrosion of the reinforcement. In order to effectively address issues of quality control, upkeep, and strategic renovation of these buildings, it becomes imperative to employ a suitable nondestructive testing and assessment technique for comprehensive surveillance aimed at early detection of hidden rebar corrosion. Infrared thermal wave imaging has arisen as a feasible method for the nondestructive examination and assessment of reinforced concrete structures. This is attributed to its ability to perform comprehensive, remote, and rapid inspections, facilitating the monitoring of subsurface rebar corrosion.

The analog separation of X-ray detector output signals by amplitude is carried out using a two-channel amplitude analyzer. The proposed model takes into account the maximum energy of X-ray photons, the energy threshold for dividing signals into low- and high-energy ones, materials and sizes of radiation-sensitive detector elements, and parameters of test objects. The model can be used to conduct research on the effect of noise caused by the quantum nature of X-ray radiation on the quality of identification of attenuating material, for example, by effective atomic number, in relation to the considered implementation of the dual energy method, as well as for the reasonable choice of parameters of the corresponding dual energy systems of digital radiography and X-ray computed tomography.</p>","PeriodicalId":764,"journal":{"name":"Russian Journal of Nondestructive Testing","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2024-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142212933","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}

Ultrasound is the only nondestructive method so far to measure the residual stress of in-service components. However, for parts with material anisotropy, such as materials processed by rolling, the measurement accuracy is highly restrained. In this paper, a rolled 316L stainless steel sample is used to study the influence of texture on the measurement of residual stress by ultrasonic surface wave. The experimental results show that the propagation velocity of surface waves in the sample has anisotropic characteristics. The wave velocity parallel to the rolling direction (0°) is the maximum, and the wave velocity perpendicular to the rolling direction (90°) is the minimum, thereby affecting the measurement accuracy. It is found that reducing the frequency of surface waves can reduce the influence of anisotropy. Therefore, a low-frequency method and modified formula are used to improve the measurement accuracy. The maximum error in the rolling direction is reduced from 21.3 to 3.6 MPa, and the maximum relative error is also reduced from 45.4 to 9.0%. The modified formula can further reduce the influence of anisotropy, with the maximum error value further reduced to 2.3 MPa, the maximum relative error reduced to 4.9%, and the surface wave detection accuracy effectively improved.</p>","PeriodicalId":764,"journal":{"name":"Russian Journal of Nondestructive Testing","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2024-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142212930","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 present article is devoted to the analysis of the first and partly fourth of listed factors. The review of reflectors, the use of which is regulated in various standards, is carried out. Advantages and disadvantages of flat-bottomed holes, segmental and corner reflectors (“notches”), lateral (SDH) and vertical cylindrical holes, and grooves are noted. Taking into account the specific features of ultrasonic wave scattering, it is noted that artificial “reflectors” such as “grooves” and SDHs are used to adjust the parameters of modern diffraction testing methods. It is recommended to expand the use of grooves, SDHs, and vertical drilling when revising the standards governing the use of conventional echo methods. The estimation of accuracy of measurement of defects parameters, first of all, the crack tip coordinates, with application of modern digital methods of information processing during ultrasonic testing is given. It is indicated that to increase the measurement accuracy and to determine the position and orientation of cracks in welds, it is necessary to create a database of digital twins of samples with artificial reflectors and products with real defects.
