“…In recent years, Hybrid AMconventional manufacturing processes are emerging as a viable way to overcome the build limitations of AM, thus enhancing the functionally and expanding reach of the AM technology [18,19]. Hybrid manufacturing processes pose a significant technological advance, allowing for component repairs [20][21][22][23], production of bimaterials [24][25][26][27][28], and manufacturing of large components with intricate designs [29][30][31][32][33]. Hybrid manufacturing techniques, consisting of both powder bed fusion and wire arc AM hold a promise to result in a manufacturing method which marks the benefits of both worlds, i.e.…”

The implementation of additive manufacturing techniques in the production of mission critical structural components is challenged by its low throughput and limited build envelope. In recent years, hybrid production methods are emerging to bridge between the build volume and high throughput of conventional production methods and the design freedom enabled by additive manufacturing. The repeatability of material properties and the quality of the interface between the additive manufactured and wrought material are crucial for the adoption of hybrid manufacturing techniques by the industry. Here, the tensile behavior and fracture toughness of a hybrid Ti-6Al-4V alloy are examined in detail. Ti-6Al-4V pre-forms were built onto a wrought Ti-6Al-4V start-plate and extracted via milling. Compact tension and uniaxial tension specimens extracted from the hybrid pre-forms demonstrated good fracture and properties with no preference for crack growth in neither the AM nor wrought materials. Microstructural characterization revealed a 40 mm transition layer into the wrought material which ends abruptly with no evidence of a gradually decaying heat-affected zone. The hybrid manufacturing approach studied here expands the current limitations of large-scale critical components with fine features and allow such structures to be produced with a higher throughput.

Residual stresses of turned Inconel 718 surface along its axial and circumferential directions affect the fatigue performance of machined components. However, it has not been clear that the axial and circumferential directions are the principle residual stress direction. The direction of the maximum principal residual stress is crucial for the machined component service life. The present work aims to focuses on determining the direction and magnitude of principal residual stress and investigating its influence on fatigue performance of turned Inconel 718. The turning experimental results show that the principal residual stress magnitude is much higher than surface residual stress. In addition, both the principal residual stress and surface residual stress increase significantly as the feed rate increases. The fatigue test results show that the direction of the maximum principal residual stress increased by 7.4%, while the fatigue life decreased by 39.4%. The maximum principal residual stress magnitude diminished by 17.9%, whereas the fatigue life increased by 83.6%. The maximum principal residual stress has a preponderant influence on fatigue performance as compared to the surface residual stress. The maximum principal residual stress can be considered as a prime indicator for evaluation of the residual stress influence on fatigue performance of turned Inconel 718.

“…Repairing steel parts using LCD has been the subject of much research in recent years. Liu et al [4,6] presented a feasibility exploration of superalloys for AISI 4140 steel repairing using LENS. However, the tensile strength and hardness value of the specimens did not meet the industrial requirements.…”

The effects of different ratios of 410L alloy and Fe–Cr–B–Si–Mo alloy powders on the microstructure and mechanical properties of laser cladding-deposited ferrous alloys were investigated. The experimental results revealed that the 410L alloy had good strength and excellent ductility due to its microstructure consisting of large elongated ferrite dendrites surrounded by a small number of martensite grains, while the Fe–Cr–B–Si–Mo alloy had high strength and poor ductility because of its eutectic microstructure composed of ferrite and Fe2B/Cr2B. As the concentration of Fe–Cr–B–Si–Mo alloy powder added to the 410L alloy powder increased, the ferrite grains became finer and the volume fraction of the eutectic increased, which eventually improved the strength and reduced the plasticity. Then, 410L + 12.5% Fe–Cr–B–Si–Mo alloy powder was successfully deposited onto AISI 1060 steel substrate via laser cladding deposition, and the mechanical properties met those of the substrate, which verified that tailoring the mechanical properties of the laser cladding-deposited alloys with a mixture of 410L and Fe–Cr–B–Si–Mo alloy powders for steel repairing applications is a feasible solution.
