“…There is also the potential for numerous intermediate heat treatments or degreasing stages, which also increase the price of the final product [18]. In addition, the flow of material during these processes can lead to the development of preferred orientation within the grains of the metal and anisotropic mechanical properties in the final product [15,20]. As such, there is a trade-off between reducing costs by minimising the number of cycles while preventing damage and promoting desirable microstructures of the final product [21].…”

“…In recent years other, more novel processes have been developed to create thin-walled seamless pipes. Maier et al [20] demonstrated a cold spray forming process, where stainless steel powder was sprayed onto a rotating aluminium tube to Figure 1 Micrographs of structure of steel wire after being subjected to various passes of cold drawing [21] Figure 2 Schematic of a cold pilgering extrusion process [16] create a 1-mm-thick layer of material. The aluminium tube was then dissolved to leave behind a thin-walled stainless-steel pipe.…”

Small diameter thin-walled pipes, typically with a diameter less than 20 mm and a ratio of outer diameter to wall thickness is 20 or above, have increasingly become a key value adding factor for a number of industries including medical applications, electronics and chemical industries. In high-energy physics experiments, thin-walled pipes are needed in tracking detector cooling systems where the mass of all components needs to be minimised for physics measurement reasons. The pipework must reliably withstand the cooling fluid operation pressures (of up to 100 bar), but must also be able to be reliably and easily joined within the cooling system. Suitable standard and/or commercial solutions combining the needed low mass and reliable high-pressure operation are poorly available. The following review of literature compares the various techniques that exist for the manufacture and joining of thin-walled pipes, both well-established techniques and novel methods which have potential to increase the use of thin-walled pipes within industrial cooling systems. Gaps in knowledge have been identified, along with further research directions. Operational challenges and key considerations which have to be identified when designing a system which uses thin-walled pipes are also discussed.

“…Studies have also shown that powder shape and size distribution contribute significantly to the quality of AM builds 21 . Other methods of incorporating nanoparticles into additive powder lots through chemical reactions or depositions have been explored; though the added complexity and expense of these techniques may limit their commercial viability 15,17,[22][23][24][25][26] .…”

Additive manufacturing currently facilitates new avenues for materials discovery that have not been fully explored. In this study we reveal how additive manufacturing can be leveraged to produce dispersion strengthened (DS), multi-principal element alloys (MPEA) without the use of traditional mechanical alloying or chemical reactions. This new processing technique employed resonant acoustic mixing to coat an equiatomic NiCoCr powder with nano-scale yttrium oxides. Then, through laser powder bed fusion (L-PBF), the coated powder was successfully consolidated into 99.9% dense parts. Microstructural analysis confirmed the successful incorporation and dispersion of nano-scale oxides throughout the build volume. Furthermore, high temperature mechanical testing of the DS alloys showed significant improvements in strength and ductility over the baseline NiCoCr. As a result, this recently discovered processing route opens a new alloy design and production path that is synergistic between additive manufacturing and dispersion strengthening, possibly enabling a new generation of high-performance alloys. Additive manufacturing (AM) techniques have broadened many aspects of component design, enabled part count reduction, and decreased commissioning time for prospective NASA hardware and industrial applications 1. Currently, the bulk of metallic AM research has been conducted on traditional alloys 2-4. Yet, AM facilitates new avenues for materials discovery that have not been fully explored 5,6. For laser powder bed fusion (L-PBF), the finely focused, laser melting of powder is analogous to welding and is thus problematic for alloys that are difficult to weld. Unfortunately, many of the alloys used for ultra-high temperature applications (>1000 °C) fall within this criterion. Therefore, there currently exists a need for high temperature alloys that can be produced through L-PBF or similar AM processes. One alloy system that has shown promise is the multi-principal element alloy (MPEA) class. The discovery and growth of this interesting new class of alloys, coined "High Entropy alloys", has coincided with the development of AM. High entropy alloy development has led to the identification of a wide range of MPEAs, such as the ternary alloy NiCoCr, which has demonstrated impressive mechanical properties over a wide range of temperatures and stresses 7,8. Recent studies have also presented favorable results from producing the NiCoCr alloy using AM 9. The success of fabricating the "Cantor alloy" (NiCoCrMnFe) and its derivatives through AM may result from the small gap between their solidus and liquidus temperatures 10 , thereby, reducing the risk of heat affected zone (HAZ) cracking and lowering residual stresses 11. Unfortunately, the phase simplicity that enhances the manufacturability of alloys such as NiCoCr will also limit their high temperature mechanical properties. An additional strengthening mechanism must be introduced, such as dispersion strengthening (DS). Dispersion strengthening, primarily through the use of oxides,...

“…= 0.5 µm) cladding tubes by depositing powder onto an Al mandrel that can later be removed. Recent work with NFAs for next generation nuclear applications used CS-deposition to make near-net shape tubes from conventional inert gas atomized 14YWT (Fe-14.8Cr-0.9W-0.5Ti-0.1Y-0.03O at%) from Los Alamos National Laboratory (LANL) by depositing onto an Al mandrel [56]. The researchers were successful in generating near-net shape tubing, but the O content of the feedstock powder (without GARS processing) was lower than needed for sufficient formation of (Y, Ti)-O nanoclusters, and consequently hardness decreased below desired lower limits after annealing due to recrystallization [56].…”
