TL;DR: In this paper, the effect of cyclic loading in the zero-to-tension scheme with an amplitude approximately corresponding to the conditional yield strength has on the magnetic and acoustic parameters of hot-rolled pipe steel, including its longitudinal and transverse magnetostriction.

TL;DR: In this paper, a 3D variant of the coherent method of projection in the spectral space (PSS) for obtaining images of reflectors on the basis of measured echo signals is considered, which allows recon-struction of reflector images with a high frontal resolution in both the main plane of an ultrasonic transducer and an additional plane.

TL;DR: In this article, the authors used super-resolution techniques in processing reflected signals in ultrasonic testing with a view to improve expert estimates of defect dimensions and shapes with the help of the Avgur holographic facility.

TL;DR: In this article, a reference-free method is proposed for determining the speed of longitudinal and transverse vertically polarized waves and the thickness of a test object based on comparing the measured and calculated echo signals reflected from the boundaries of the test object when using an antenna array operating on a zero tilt angle wedge in the double scanning mode.

TL;DR: In this article, two algorithms for the automatic determination of flaw parameters during ultrasonic testing of welded joints with a high level of structural background noises are considered; the first algorithm is used to identify zones where flaws may be located and the second processing algorithm is intended to determine the flaw's actual length and height.
