“…The grain boundary precipitate coarsening mechanism also likely contributes to the drop in alloy yield strength at increasing temperatures for the HTPSAs with Zr/Sc. Among the AM CDAs, grain refinement by TiB 2 in Al-Cu-Mg-Ni-Fe-Ti-B and TiCN in Al-Si-Mg likely provides an increment in tensile strength [262,263]. In both studies, the ceramic-modified AM alloys outperformed their un-modified wrought and cast counterparts at elevated temperatures, suggesting that the dispersions aid in high-temperature performance by pinning grain boundaries.…”

“…Nevertheless, the high volume fraction of TiC reinforcement contributes to significant strengthening by Orowan looping, load transfer, and a grain refinement effect. The remarkable compressive strength for Al-29.9Nd-7.6Ni-3.1Co is likely due to the exceptionally high volume fraction of intermetallic phases [126], Al-2.9Mg-2.1Zr [47], Al-14.1Mg-0.47Si-0.31Sc-0.17Zr [115], Al-8.6Cu-0.45Mn-0.90Zr [65], Al-12.1Si-1.4Ni-1.4Fe [277], Al-2.3Cu-1.6Mg-1.1Ni-0.8Fe-3.5Ti-1.2B [263], Al-10Si-0.3Mg with 2 vol.-% 2-4μm-TiCN [262], CP-Al with 35 vol.-% TiC [155], and Al-29.9Nd-7.6Ni-3.1Co [278]. For comparison, data for AM Al-10Si-0.3Mg are also shown [279].…”

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.

Aluminum (Al) and its alloys are the second most used materials spanning industrial applications in automotive, aircraft and aerospace industries. To comply with the industrial demand for high-performance aluminum alloys with superb mechanical properties, one promising approach is reinforcement with ceramic particulates. Laser powder-bed fusion (LPBF) of Al alloy powders provides vast freedom in design and allows fabrication of aluminum matrix composites with significant grain refinement and textureless microstructure. This review paper evaluates the trends in in situ and ex situ reinforcement of aluminum alloys by ceramic particulates, while analyzing their effect on the material properties and process parameters. The current research efforts are mainly directed toward additives for grain refinement to improve the mechanical performance of the printed parts. Reinforcing additives has been demonstrated as a promising perspective for the industrialization of Al-based composites produced via laser powder-bed fusion technique. In this review, attention is mainly paid to borides (TiB2, LaB6, CaB6), carbides (TiC, SiC), nitrides (TiN, Si3N4, BN, AlN), hybrid additives and their effect on the densification, grain refinement and mechanical behavior of the LPBF-produced composites.

Many industries such as aerospace, power generation, and ground transportation demand structural materials with high specific strength at elevated temperatures. Up until now, many types of heat‐resistant materials including Ni‐based superalloys, intermetallic compounds, and dispersion‐strengthened alloys have been developed for specific applications in these industries. Moreover, with the recent development of additive manufacturing techniques, these industries can now benefit from the rapid prototyping abilities, geometric freedom, and increased mechanical properties that can be achieved through various additive manufacturing processes. With this in mind, the progress made in additive manufacturing of heat‐resistant intermetallic compounds and ceramic dispersion alloys is herein examined. A brief introduction is provided on the target industries, applications, and the compositions of heat‐resistant alloys of current research interest. Then, recent research on heat‐resistant intermetallic compounds and ceramic dispersion alloys fabricated by additive manufacturing processes such as laser powder bed fusion, laser direct energy deposition, and electron‐beam powder bed fusion are reviewed with information provided on microstructure, processing parameters, strengthening mechanisms, and mechanical properties. Finally, an outlook is provided with future research suggestions.
