In the field of plastic forming, ultrasonic vibration has the advantages of small forming force and high forming quality, and it has been introduced into a single-point incremental plastic forming technique with high flexibility and high precision. The ultrasonic vibration single-point incremental compound forming technology with all the above advantages has been achieved. To reveal the variation tendency of the forming force under ultrasonic vibration and single-point incremental coupling, the process parameters (layer spacing, tool head radius, and feed rate) and vibration parameters (frequency and amplitude) on the forming force of the composite technology were quantitatively analyzed by theory, simulation, and experiment. The simulation and experimental results showed that ultrasonic vibration can significantly reduce the forming force of the composite technology. Compared with the simulation results, the theoretical results are not only closer to the experimental results but also have a shorter computation time and better prediction effect on the forming force. The change in the process parameters has a linear effect on the forming force, the nonlinearity of the vibratory parameters influences the forming force, and the frequencies and amplitudes in a suitable range allow the forming force to reach a minimum value. These conclusions have some significance for further studies on the ultrasonic vibratory single-point incremental composite forming technology.

“…Their results showed far higher strength of the ARB-produced specimens. Wang et al [20] investigated the microstructure, texture, and mechanical properties of ARB-produced AA1060 sheets at cryogenic temperatures. They repeated successive cycles in these samples that resulted in a significant increase in the tensile strength along with a dramatic decline in the elongation.…”

“…shows the evolution of mechanical properties of AA1050 specimens with the increase of the WARB process cycle numbers. Up to 5 cycles, there is an increasing trend for strength.Greater strength, and less elongation of these specimens after the ARB process are regarded as the natural behavior of the metals[32,20]. Also, up to five cycles, yield (YS) and ultimate tensile strengths (UTS) are enhanced as the cycle's number increases.The first cycle has an important effect on the mechanical characteristics of the specimen.…”

In this study, the fracture toughness of the multi-layered commercial pure aluminum samples (AA1050) prepared by warm accumulative roll bonding (WARB) was investigated for the first time. Based on the ASTM E561 standard, the R-curve method was utilized to measure the plane stress fracture toughness. Compact tension (CT) samples were prepared from the sheets that were processed by different ARB cycles. Mechanical properties, microstructure, and fracture surfaces of the CT samples were studied by uniaxial tensile test, electron backscatter diffraction (EBSD), and scanning electron microscopy (SEM), respectively. By increasing the number of WARB cycles, fracture toughness increased; after five cycles, 78% enhancement was observed compared to the pre-processed state. A correlation was seen between the fracture toughness variations and ultimate tensile strength (UTS). WARB enhanced UTS up to 95%, while the grain size showed a reduction from 35 to 1.8 µm. Measured fracture toughness values were compared with the room temperature ARB outcomes, and the effective parameters were analyzed. Fractography results indicated that the presence of tiny cliffs and furrows and hollow under fatigue loading zones and shear ductile rupture in the Quasi-static tensile loading zone.

The 7075 aluminum alloy was an important structural material in the field of aeronautics and astronautics. With the development of this field, the requirements for its comprehensive properties were increasing. A novel casting method, the impact jet solid-liquid compound casting, was adopted to fabricate the 3A21/7075 aluminum alloy cladding material. Retrogression and reaging (RRA) treatment was further applied to the 3A21/7075 aluminum alloy cladding material in order to investigate the influence of RRA on microstructure and microhardness of the 3A21/7075 aluminum alloy cladding material. Then, the electron backscattered diffraction (EBSD) technique and the transmission electron microscope (TEM) together with the energy dispersive spectrometer (EDS) and the hardness test were utilized to analyze the influence of RRA treatment on microstructure and hardness of the 3A21/7075 aluminum alloy cladding material. The research results showed the 3A21/7075 aluminum alloy cladding material had better deformability. The amount of fine and dispersed phases precipitated in grains was in favor of improving the comprehensive mechanical properties of the 3A21/7075 aluminum alloy cladding material. This research might provide data and a theoretical approach for the engineering application of the 3A21/7075 aluminum alloy cladding material.
