“…ЛУ метод похож на традиционный ультразвуковой метод контроля, однако вместо использования пьезоэлектрических преобразователей для генерации и приема короткого акустического зондирующего импульса в ЛУ методе используется короткий (обычно < 10 ns) лазерный импульс для генерации короткого (< 100 ns) и широкополосного (1.9 MHz) акустического зондирующего импульса за счет оптико-акустического эффекта [13]. В этом случае хорошо задемпфированные пьезоэлектрические преобразователи могут использоваться для приема обратно рассеянного акустического поля в широком диапазоне частот [13][14][15]. ЛУ метод -эффективный и быстродействующий, поскольку для генерации зондирующего ультразвукового сигнала используется лазерный импульс, а ширина полосы зондирующего импульса может быть достаточно широкой (от единиц до десятков MHz).…”

“…Это позволяет проводить широкополосный ультразвуковой контроль объектов и эффективно разделять генерацию и обнаружение ультразвуковых сигналов для увеличения отношения сигнал/шум. Кроме того, поперечный профиль акустического пучка повторяет гладкий поперечный профиль освещающего лазерного луча, таким образом практически устраняя боковые лепестки [14].…”

“…Nondestructive evaluation techniques, for instance, X-ray diffraction, acoustic emission, ultrasonic attenuation, and velocity measurement, etc., are implemented for the detection and the characterization of thermal aging and damage in metal materials. In recent years, linear laser ultrasonic techniques have been widely used in the non-destructive testing of physical and mechanical properties of materials [4][5][6][7][8][9][10][11][12][13]. However, acoustic parameter variations measured by linear ultrasonic technology are relatively small in response to early damage and change of materials and structures [14][15][16][17].…”

Nonlinear acoustic techniques are established tools for the characterization of micro-inhomogeneous materials with higher sensitivity, compared to linear ultrasonic techniques. In particular, the evaluation of material elastic quadratic nonlinearity via the detection of the second harmonic generation by acoustic waves is known to provide an assessment of the state variation of heat treated micro-structured materials. We report on the first application for non-destructive diagnostics of material thermal aging of finite-amplitude longitudinal acoustic pulses generated and detected by lasers. Finite-amplitude longitudinal pulses were launched in aluminum alloy samples by deposited liquid-suspended carbon particles layer irradiated by a nanosecond laser source. An out-of-plane displacement at the epicenter of the opposite sample surface was measured by an interferometer. This laser ultrasonic technique provided an opportunity to study the propagation in aluminum alloys of finite-amplitude acoustic pulses with a strain up to 5 × 10−3. The experiments revealed a signature of the hysteretic quadratic nonlinearity of micro-structured material manifested in an increase of the duration of detected acoustic pulses with an increase of their amplitude. The parameter of the hysteretic quadratic nonlinearity of the aluminum alloy (Al6061) was found to be of the order of 100 and to exhibit more than 50% variations in the process of the alloy thermal aging. By comparing the measured parameter of the hysteretic quadratic nonlinearity in aluminum alloys that were subjected to heat-treatment at 220 °C for different times (0 min, 20 min, 40 min, 1 h, 2 h, 10 h, 100 h, and 1000 h), with measurements of yield strength in same samples, it was established that the extrema in the dependence of the hysteretic nonlinearity and of the yield strength of this alloy on heat treatment time are correlated. This experimental observation provides the background for future research with the application goal of suggested nonlinear laser ultrasonic techniques for non-destructive evaluation of alloys’ strength and rigidity in the process of their heat treatment.

“…Raguvarun et al used both XCT and UT methods to evaluate the porosity of titanium samples fabricated by gas tungsten arc welding (GTAW), finding that a change in process parameter, namely wire feed, significantly affected the porosity of the sample fabricated by GTAW [10]. However, owing to the relatively large size of XCT equipment and the coupling agent needed for UT, their application has been limited [2].The laser ultrasonic testing (LUT) technique has been around for about 20 years, which can be applied to the non-contact and non-destructive inspection in many areas, including nondestructive inspection, quality assurance testing, and structural health monitoring [11,12]. The performance of LUT technique has been constantly improved in recent years by advances in material sciences and fabrication technology [13].…”

For a non-contact, non-destructive quality evaluation, laser ultrasonic testing (LUT) has received increasing attention in complex manufacturing processes, such as additive manufacturing (AM). This work assessed the LUT method for the inspection of internal hole defects in additive manufactured Ti-6Al-4V part. A Q-switched pulsed laser was utilized to generate ultrasound waves on the top surface of a Ti-6Al-4V alloy part, and a laser Doppler vibrometer (LDV) was utilized to detect the ultrasound waves. Sub-millimeter (0.8 mm diameter) internal hole defect was successfully detected by using the established LUT system in pulse-echo mode. The method achieved a relatively high resolution, suggesting significant application prospects in the non-destructive evaluation of AM part. The relationship between the diameter of the hole defects and the amplitude of the laser-generated Rayleigh waves was studied. X-ray computed tomography (XCT) was conducted to validate the results obtained from the LUT system.
