“…In the HAZ, the ferrite grains grow within the austenite grains until the long strip austenite grains are separated. In the WM, allotriomorphic grain boundary austenite (GBA), needle‐like widmanstatten austenite (WA), and tiny intragranular austenite (IGA) are formed sequentially in the ferrite 2,35 …”

“…In the WM, allotriomorphic grain boundary austenite (GBA), needle-like widmanstatten austenite (WA), and tiny intragranular austenite (IGA) are formed sequentially in the ferrite. 2,35 Generally speaking, the microstructure changes of the specimens by surface treatment are mainly reflected in two aspects. 11 First, plastic deformation occurs in the surface area of the specimen, and the plastic deformation of the material was caused by the slippage of the internal structure of the material.…”

The cruciform welded joint is a weak position of filter press to cause fatigue failure under cyclic conditions. In this study, cavitation jet peening (CJP) treatment is proposed to improve the fatigue life of SAF2205 cruciform welded joints. The effects of different CJP treatment positions on the residual stress, microstructure, and microhardness were studied. The results show that different CJP treatment positions have different on residual stresses and fatigue life. The order of the residual stress in fracture position from large to small is the fully treated specimen, untreated specimen, one-sided treated specimen, and diagonal treated specimen, which is exactly opposite to the order of fatigue life from large to small. After the diagonal CJP treatment, the fatigue life is increased by up to 242.19%, and the residual stress at the weld toe is reduced by more than 80%. A strengthening layer with thicknesses of about 400 μm is formed.

“…Wei et al [1] proposed that the <111> hard orientation had the effect of concentrating the residual compressive stress in Cu-Ni-Si coldrolled sheet, while the effect of the <211> medium orientation was not obvious. Zohrevand et al [2] found that ultrasonic treatment effectively reduced the internal stress of the duplex structure. The <111> and <110> deformed texture gradually decreased, but the <100> texture was strengthened.…”

Thermal-ultrasonic coupling residual stress release experiment of C19400 copper alloy strip was carried out with self-made experimental device under different ultrasonic amplitudes. The texture evolution and residual stress relaxation of the strip were systematically studied. The results show that, with the increasing ultrasonic amplitude, the strength of cubic texture decreased, while the strength of Brass texture increased. Low-angle grain boundaries were mainly formed in brass texture owing to its high Taylor factor. The slip and interaction of dislocations lead to the grain rotation and the change in texture type, which was the main reason for the relaxation of residual stress.

“…With the wide application of power ultrasound in advanced machining fields, sandwich piezoelectric transducers are valued and studied in ultrasonic milling [ 1 , 2 ], ultrasonic casting [ 3 , 4 ], and ultrasonic vibration for machining residual stress removal [ 5 , 6 , 7 , 8 , 9 ] because of their good electromechanical conversion characteristics. Although the structure and performance of piezoelectric ceramic transducers for different ultrasonic processing fields are not consistent, the inherent frequency of sandwich piezoelectric transducers is the most important performance parameter, which is the key to achieving high power output and high-efficiency energy conversion in practical applications.…”

Great progress has been made in the field of ultrasonic processing in recent years, and piezoelectric ceramic transducers have been widely used as drive sources. In this paper, a sandwich piezoelectric ceramic transducer is designed, and the vibration of each part of the transducer is analyzed by elastic mechanics and piezoelectric theory. According to its mechanical and electrical boundary conditions, the vibration model of the piezoelectric transducer was established. Based on the equivalent elastic modulus method for simplifying the pre-stressed bolts into a one-dimensional transducer vibration model, the relationship between the one-dimensional axial response frequency of the transducer and the length of each component was obtained. Based on the half wavelength theory, a transducer with the vibration node in the crystal stack and an inherent frequency of 15 kHz was designed and fabricated. In order to verify the natural frequency and vibration characteristics of the piezoelectric transducer, a laser vibration measurement system was built in this study. The vibration characteristics of the transducer under different parameters such as voltage and frequency were analyzed, and the accuracy of the vibration model was verified. The vibration states of the end surface of the transducer and the radial surface were evaluated at the first-order inherent frequency and second-order inherent frequency. The results show that the equivalent simplified model established in this study can effectively design the inherent frequency of the transducer, and the operation at the first-order inherent frequency meets the one-dimensional assumptions of this study. The transducer operating conditions measured in this study also provide a more detailed reference for ultrasonic processing applications.
