“…In recent years, demand for the great comprehensive mechanical properties of IN625 alloy has increased seriously with the continuous expansion of application areas. During processing, the microstructure and mechanical properties are greatly affected by the coupled thermo-mechanical effects [5]. Therefore, it is vital to meticulously analyze the deformation behavior of IN625 alloy at different temperatures and strain rates.…”

Hot deformation behavior and the microstructural evolution of Inconel 625 superalloy plates are investigated by hot compression tests in a range of working temperatures (800–1050 °C) and strain rates (0.001–1 s−1). The microstructural observation shows that a strong <110> texture forms when the processing temperature is below 950 °C, whose intensity decreases with the increases of the temperature, and it disappears when compressing above 950 °C. During the compression test, twin-related dynamic recrystallization (DRX) occurs in the investigated temperature range, and the intensity of twin-related DRX increases with the increases of the temperature. In addition, as the temperature increases, the intensity of continuum DRX decreases.

“…In additive manufacturing, process parameters such as the shape and size of the powder material, laser power, hatching speed, hatching distance, and layer thickness significantly affect the mechanical properties such as dimensional accuracy and surface quality part [8]. In the literature academic studies are examined, the materials used in additive manufacturing processes are steel and stainless steel [9,10], titanium alloys [11], aluminium alloys [12], nickel-based alloys [13], cobalt-chromium alloys [14]. Titanium alloy material has high surface quality, high strength, excellent biocompatibility, low density, good corrosion resistance, high fatigue resistance, lightness, strength to shear deformation, and controllable porosity.…”

The most critical component of Industry 4.0, the new face of the machinery-manufacturing industry sector, is metal additive manufacturing. Laser-based additive manufacturing techniques are dominant for metal additive manufacturing today. In this study, the metal alloy studied is Ti-6Al-4V, one of the essential Ti alloys used in more than 50% of all commercial Ti applications. Ti-6Al-4V parts produced by additive manufacturing are used in the biomedical, aerospace-defence industry, and industrial areas due to their high strength, fatigue behaviour, fracture strength, good corrosion resistance, and biocompatibility. In the study, samples of Ti6Al4V alloy were produced with different manufacturing parameters by the direct metal laser sintering (DMLS) method, which is one of the powder bed fusion methods. Then, the surface qualities of the samples were processed by milling and wire EDM. The effects of machining operations on the surface roughness of the samples were investigated and compared with the surface roughness obtained from the samples produced by the DMLS method. After the optical microscope images of the samples were taken, the physical and surface morphology were examined. Although the mechanical properties of the parts manufactured by DMLS methods were higher, the samples with machining presented higher machinability with lower forces, lower surface roughness. the This is explained that mechanical properties of samples of Ti6Al4V alloy in additive manufacturing are highly dependent on the rapid cooling of the material. Results show that samples of Ti6Al4V manufactured by additive manufacturing has been possible using with machining.

In this work, the external longitudinal magnetic field hybrid metal inert gas welding (M-MIG) additive manufacturing method is employed to produce the Ti-6Al-4V alloy part. The effect of process parameters on the droplet transfer formation and microstructure of the part was studied by a high-speed camera, optical microscope, and electron backscattered diffraction. The results showed that a typical short-circuiting transfer was obtained with the wire feeding speed of 2 m/min–4 m/min. An external longitudinal magnetic field had an obvious effect on the arc shape. The uniform formation of the deposition layer was obtained with the wire feeding speed of 4 m/min. The width of M-MIG deposition layer was greater than that of the MIG, and the width of M-MIG deposition layer was increased with the increase of the magnetic excitation current. The microstructure of the deposition layer was mainly comprised of acicular martensite α’ and massive martensite αm. In addition, the β grain size in the M-MIG was less than that of the MIG. The average microhardness of the MIG deposition layer was 281.6 HV, which was less than that of M-MIG.
