“…The recent surge in interest towards fabricating functionally graded materials (FGMs) [22][23][24], which feature a gradual change in the mixture ratio of two or more materials based on location, has opened up new avenues in materials engineering. Titanium, with its high-strength and lightweight characteristics, emerges as an ideal candidate for incorporation into FGMs [23,24].…”

“…DED, in particular, is extensively used for its ability to deposit metal materials in a single process step, forming dense, thin-walled, or large-volume metal parts through the pneumatic injection of powder into a laser-induced melt pool. This technique has sparked numerous studies focused on fabricating FGMs, including heterogeneous metal systems, via AM technology for components unfeasible with traditional methods like welding [17,22]. Additionally, the use of high-power energy sources such as lasers in these processes facilitates the creation of unique microstructures, enhancing mechanical strength due to rapid heating and cooling.…”

Ti–6Al–4V alloys are known for their suboptimal tribological properties and are often challenged by durability issues under severe wear conditions. This study was conducted to enhance the alloy’s wear resistance by forming a hardened surface layer. Utilizing directed energy deposition (DED) additive manufacturing with a diode laser, vanadium carbide particles were successfully integrated onto a Ti–6Al–4V substrate. This approach deviates from traditional surface enhancement techniques like surface hardening and cladding, as it employs DED additive manufacturing under parameters akin to those used in standard Ti–6Al–4V production. The formed vanadium carbide layer achieved a remarkable thickness of over 400 µm and a Vickers hardness surpassing 1500 HV. Pin-on-disk test results further corroborated the enhanced surface wear properties of the Ti–6Al–4V alloy following the additive-manufacturing process. These findings suggest that employing vanadium carbide additive manufacturing, under conditions similar to the conventional DED process with a diode laser, significantly improves the surface wear properties of Ti–6Al–4V in metal 3D-printing applications.

“…The microstructure of metal materials produced through 3D printing exhibits a wide range of forms, primarily influenced by material properties and process variables such as heat input, scanning speed, layer thickness, and others. In traditional manufacturing processes, system components must be separately fabricated and then combined during post-processing to create composite parts 2,3,[15][16][17][18][19][20][21][22] . As a result, multiple machines and welding or joining processes along assem-bly lines are required before the final product is created.…”

Metal Additive Manufacturing (AM) or 3D printing garners attention for economically producing components with superior strength, durability, and corrosion resistance. The microstructure, influenced by factors like heat input, scanning speed, and layer thickness, shapes metal materials intricately in 3D printing.Unlike traditional manufacturing with separate fabrication and post-processing, Multi Materials AM (MM-AM) streamlines the construction of composite structures in a single step using a single machine. Although initial MM-AM, especially inpolymer 3D printing, was simpler, the shift to metal-based MM-AM presents challenges. The distinctive bonding style in MM-AM facilitates robust connections between different metals, minimizing stress concentration and simplifying the joining of diverse metals. Challenges like intermetallic compound formation, residual stress, and material-specific issues leading to cracks persist. Ongoing research focuses on metallurgy, process optimization,and computational simulation to overcome these hurdles. This review delves into current research trends in multi-material AM, identifying pathways for technological advancements. It discusses the application of Directed Energy Deposition (DED)in stacking austenitic and ferritic metals for nuclear power plant cooling system piping's gradient-form safe-ends. The study emphasizes advanced manufacturing techniques for developing functionally graded materials and dissimilar metal joints, highlighting the transformative potential of additive manufacturing across industries.

“…Titanium alloys and stainless steels are two of the most widely used materials in many critical applications owing to their superior mechanical properties, excellent corrosion resistance, and biocompatibility. Welding these materials is of great interest in many industries, including the aerospace, marine, and biomedical fields [ 1 , 2 , 3 , 4 , 5 , 6 , 7 ]. However, welding titanium and stainless steel alloys is challenging due to their inherently different metallurgical properties, which can lead to the formation of brittle intermetallic compounds (IMCs) and thermal distortion during welding [ 8 ].…”

The development of robust and efficient methods for constructing and joining complex metal specimens with high bonding quality and durability is of paramount importance for various industries, e.g., aerospace, deep space, and automobiles. This study investigated the fabrication and characterization of two types of multilayered specimens prepared by tungsten inert gas (TIG) welding: Ti–6Al–4V/V/Cu/Monel400/17-4PH (Specimen 1) and Ti–6Al–4V/Nb/Ni–Ti/Ni–Cr/17-4PH (Specimen 2). The specimens were fabricated by depositing individual layers of each material onto a Ti–6Al–4V base plate, and subsequently welding them to the 17-4PH steel. The specimens exhibited an effective internal bonding without any cracks, accompanied by a high tensile strength, with Specimen 1 exhibiting a significantly higher tensile strength than Specimen 2. However, the substantial interlayer penetration of Fe and Ni in the Cu and Monel layers of Specimen 1 and the diffusion of Ti along the Nb and Ni–Ti layers in Specimen 2 resulted in a nonuniform elemental distribution, raising concerns about the lamination quality. This study successfully achieved elemental separation of Fe/Ti and V/Fe, which is vital for preventing the formation of detrimental intermetallic compounds, particularly in the fabrication of complex multilayered specimens, representing the prime novelty of this work. Our study highlights the potential of TIG welding for the fabrication of complex specimens with high bonding quality and durability.
