“…Fan et al [27] produced TiC/(TC18 + TC4) composites with HS materials. Compared to Materials 2024, 17,1922 2 of 14 the homogeneous materials, they found that the HS materials have higher strength and ductility (fracture strength of 1150 MPa and uniform elongation of 5%). Jiang et al [28] manufactured TC4-Nb-NiTi alloy components using multi-wire arc additive manufacturing and tested their microhardness (393 HV) and ultimate compressive strength (1420 MPa).…”

“…Due to the plastic incompatibility between the hard and soft zones in HS materials [8], geometrically necessary dislocations (GNDs) in the soft zones pile up and accumulate near the zone boundaries, generating back stress in the soft zones and positive stress in the hard zones, which collectively produce heterogeneous deformation-induced (HDI) stresses, thereby increasing the strength and ductility of the material [9][10][11]. HS materials [12] include heterogeneous lamellar structured materials [13], gradient structured materials [14][15][16][17][18], lamellar structured materials [19][20][21], and bimodal/multimodal structures [22,23]. HS materials without metallurgical bonding interfaces have been applied in the field of armor, such as ceramic/metal composite armor, which has attracted a lot of attention for its excellent ballistic performance [24,25].…”

Using the Split Hopkinson Pressure Bar technique, strain-limited dynamic compressive loading experiments were performed on TA1/TA15 heterostructure (HS) materials. The plastic deformation mechanisms, fracture forms, and energy absorption properties of an HS material with a metallurgical bonding interface (MB) and an HS material without a metallurgical bonding interface (NMB) are compared and analyzed. The results show that there is no significant difference between the two deformation mechanisms. The fracture forms are all “V-shaped” fractures within the TA1 part. The NMB was carried for 57 μs before failure and absorbed 441 J/cm3 of energy. The MB was carried for 72 μs before failure and absorbed 495 J/cm3 of energy. Microstructure observations show that there is a coordinated deformation effect near the MB interface compared to the NMB, with both TA1 and TA15 near the interface carrying stresses. This causes an enhancement of the MB load-bearing time and a 12% increase in energy absorption.

“…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.

“…The joining of titanium (Ti) with dissimilar materials such as stainless steel and copper (Cu) is of great technological significance owing to widespread application of such hybrid components in various engineering sections, ranging from Ti sputtering target manufacturing to the heat exchanger fabrication specific to nuclear power generation industry [1][2][3][4]. It has been long recognized to be a challenging task to achieve strong and reliable dissimilar joining of Ti and Cu, primarily because of poor metallurgical compatibility and notable mismatch in physical properties of Ti/Cu system [5,6].…”

Improving bonding strength and reliability of brazed titanium/copper dissimilar joint using vanadium interlayer

Conventional practice of brazing titanium (Ti) to copper (Cu) using Ag-28Cu eutectic filler alloy is of limited success because of the generation of brittle Ti-Cu intermetallic compounds (IMCs). The bonding strength is unsatisfactory owing to embrittlement of IMCs, and it is difficult to reproduce the bonding strength as the joint microstructure is highly sensitive to brazing parameters. In the current study, it was demonstrated that the formation of such undesirable IMCs can be suppressed and strong Ti/Cu joint can be obtained by brazing at 850 °C using a refractory vanadium (V) interlayer 15 μm in thickness deposited on Ti substrate, in combination with an Ag-Cu-Ti active filler alloy. The V interlayer successfully blocked the interaction between Ti and filler alloy. Bonding mechanisms of the resultant joint can be deduced to be a synergy of active brazing in the V/Ag-Cu-Ti/Cu half and solid-state diffusion bonding at the Ti/V interface. The thus developed joint was comprised of continuous Ti-V solid solution, unconsumed V interlayer and remaining filler alloy. Attributed to elimination of brittle IMCs at joint interface, excellent bonding strength of ∼220 MPa which is comparable with strength of Cu base metal was achieved. Moreover, since the joint evolution was dominated by sluggish solid-state diffusion at the Ti/V interface and very limited erosion of V interlayer by the Ag-Cu-Ti filler, desirable IMC free joint can be obtained over a wide range of brazing time (2 ∼ 5 min), enabling outstanding reliability of the high bonding strength.
