The results indicate that the low-temperature magnetic field technology effectively combines the advantages of low temperature and magnetic fields, enhancing the material's machinability.

The current study aims to achieve a continuous and uniform metal transfer from a 4 mm diameter mild steel wire using a developed IH-DED system. A unique multi-loop and multi-turn induction coil is designed to investigate the metal transfer mode and the frequency by varying the coil current and wire feed speed (WFS). The role of Lorentz force for the molten droplet detachment is analyzed in pertinent to the DED process. A high-speed camera is employed to capture the droplet necking and transfer mechanism to the substrate. The mode of metal transfer is observed as uniform globular form for the coil current range of 300 A − 400 A. However, the droplet detachment takes significant time to produce inconsistent droplets and non-uniform deposition at relatively high current. Hence, the coil current and WFS are optimized for continuous droplet formation at the end location of the induction coil and to ensure uniform deposition. The widening of Lorenz force distribution mainly delays the droplet detachment. However, the metal transfer rate improves significantly by enhancing the WFS (&gt;200 mm/min) at relatively high current (&gt;350 A). The WFS of 400 mm/min and coil current of 400 A produces a uniform and straight bead where the maximum deposition rate is achieved as 43 g/min.

In this study, based on the orthogonal cutting model, the effect of vibration on the cutting process is analyzed. Based on vibration theory, the formulas for calculating the displacement transmissibility of twist drill and the amplitude of cutting edge of twist drill are derived. Based on drilling principle, the influence of vibration parameters on the actual feed per tooth is discussed. By analyzing the relationship between drilling parameters and vibration parameters, the different effects of longitudinal vibration on each cutting edge of the twist drill are expounded. A novel thrust force prediction model of LFVD (Low-Frequency Vibration Drilling) based on drilling parameters, vibration parameters and the twist drill characteristics was derived by simplifying the twist drill as a linear link with multiple inputs and outputs. The theoretical research shows that the effect of longitudinal vibration on the chisel edge is equivalent to main motion direction vibration, the effect on the major cutting edge is equivalent to cut depth and feed direction vibration simultaneously, and the effect on the minor edge is equivalent to feed direction vibration. If the amplitude of the cutting edge of the twist drill relative to the workpiece is smaller than 1/4 of the feed per revolution, but does not meet the intermittent cutting conditions, when the frequency/rotation ratio is odd or close to odd, it is continuous cutting. With the increase of amplitude, the chip thickness difference increases, and the chip breaking effect is enhanced. If the amplitude is greater than or equal to 1/4 of the feed per revolution, when the frequency/rotation ratio is odd or close to odd, it is intermittent cutting, complete chip breaking or good chip breaking can be achieved. The amplitude of the thrust force fluctuation component will increase with the increase of the vibration amplitude relative to the workpiece. The thrust force fluctuation component contains both of the component proportional to the vibration amplitude relative to the workpiece and the inertia force of the twist drill. The statistical results of drilling experimental data show that the accuracy of the thrust force average calculated by the prediction model established in this study can reach 86% ∼ 95%. The confirmatory experiments of LFVD show that the errors of the maximum and the average value of thrust force, as well as the amplitude of the harmonic component calculated by the thrust force prediction model are 1.7%, 10.6% and 3.6%, when drilling CFRP, respectively and 1.5%, 1.4% and 5.5% respectively when drilling titanium alloys.

Pulsed laser welding with a low duty cycle has emerged as an effective technique to address these issues, due to its flexible parameters and low heat input. Nevertheless, the microstructure evolution, the generation and propagation of cracks in 7xxx aluminum alloy during pulsed laser welding is still unclear. In this study, pulsed laser welding of 7075 aluminum alloy with varying welding parameters was conducted and the typical microstructure of the welded joint was characterized.

Crack-free welded joints were obtained from the welding with filler strips cut from the same 7075 sheet.

In this study, WAAM deposits of SS316L are made with four different dwell times (0 s, 15 s, 30s, and 45 s), and the tensile performance was evaluated along three different directions (0°, 45°, and 90°).

Microstructural analysis revealed the presence of austenite (γ) and residual ferrite (δ). The microstructure obtained from electron backscattered diffraction maps indicates fiber texture, i.e., crystallographic orientation and presence of second-phase particles, which leads to anisotropy with mechanical properties.
