“…The results obtained in the course of this investigation into the structure of composite SHS materials are in agreement with the data provided in research works [4][5][6][7]30] in the body of literature. The authors of these research works have used self-propagating hightemperature synthesis to fabricate composites where each composite comprises a matrix with ceramic particles distributed throughout its volume.…”

“…Alloys based on Ti [1,2] and Ni [3][4][5] are well studied, and they have proven to be a good fit for use in the fabrication of functional parts using additive manufacturing (AM) technologies. However, with the development of aerospace, automobile and ship-building industries, materials with advanced physico-mechanical characteristics are in demand.…”

Currently, metal–matrix composite materials are some of the most promising types of materials, and they combine the advantages of a metal matrix and reinforcing particles/fibres. Within the framework of this article, the high-temperature synthesis of metal–matrix composite materials based on the (Ni-Ti)-TiB2 system was studied. The selected approaches make it possible to obtain composite materials of various compositions without contamination and with a high degree of energy efficiency during production processes. Combustion processes in the samples of a 63.5 wt.% NiB + 36.5 wt.% Ti mixture and the phase composition and structure of the synthesis products were researched. It has been established that the synthesis process in the samples proceeds via the spin combustion mechanism. It has been shown that self-propagating high-temperature synthesis (SHS) powder particles have a composite structure and consist of a Ni-Ti matrix and TiB2 reinforcement inclusions that are uniformly distributed inside it. The inclusion size lies in the range between 0.1 and 4 µm, and the average particle size is 0.57 µm. The obtained metal-matrix composite materials can be used in additive manufacturing technologies as ligatures for heat-resistant alloys, as well as for the synthesis of composites using traditional methods of powder metallurgy.

“…Reviews on challenges and opportunities associated with AM of fatigue-resistant materials have been published [309,310] [318]) and the lower temperature studies on Al-Si-based alloys can provide expectations for elevated-temperature AM Al alloy classes considered in this review and are summarised below. Additionally, since the effect of surface oxidation on crack initiation behaviour is not a strong function of temperature in Al alloys, the underlying fatigue mechanisms are expected to be similar in a wider temperature range.…”

Research on powder-based additive manufacturing of aluminium alloys is rapidly increasing, and recent breakthroughs in printing of defect-free parts promise substantial movement beyond traditional Al-Si-Mg) systems. One potential technological advantage of aluminium additive manufacturing, however, has received little attention: the design of alloys for use at T >~200°C, or~1/2 of the absolute melting temperature of aluminium. Besides offering lightweighting and improved energy efficiency through replacement of ferrous, titanium, and nickel-based alloys at 200-450°C, development of such alloys will reduce economic roadblocks for widespread implementation of aluminium additive manufacturing. We herein review the existing additive manufacturing literature for three categories of potential hightemperature alloys, discuss strategies for optimizing microstructures for elevatedtemperature performance, and highlight gaps in current research. Although extensive microstructural characterisation has been performed on these alloys, we conclude that evaluations of their high-temperature mechanical properties and corrosion responses are severely deficient.

“…Methods to extract more meaningful mechanical properties from instrumented indentation testing is an enduring endeavor (e.g., [21][22][23][24][25]). Aside from indentation, there have been efforts to improve the throughput of traditional mechanical tests, tensile [8] and fatigue [26,27] testing, as well as develop new tests that capture mechanical performance such as parallel blow forming [28]. Here we note that there are challenges and sacrifices typically made with high-throughput mechanical tests.…”
