“…Furthermore, the weakening of the magnetic properties is also influenced by the density of the magnetic composite samples. With a greater bakelite composition, the magnetic particle loading decreases, which in turn tends to decrease the density and magnetic properties, because Br and BHmax are in direct proportion to the relative density of the magnet [20].…”

Composite hard magnet NdFeB materials were made using powdered rapidly quenched Nd-Fe-B (MQP-B) and polymers (bakelite). The proportion of the polymer matrix was varied (2.0, 5.0, 7.0, and 10 wt.%). The composite hard magnet NdFeB materials were compacted using one-sided uniaxial hot pressing at 160 °C for 20 min. The bulk density of the composite hard magnet NdFeB was measured using the Archimedes method. Compression tests were carried out using the Universal Testing Machine. The results show that a permanent magnet composite with a 2 wt.% bakelite binder composition exhibits higher bulk density and superior magnetic parameters (i.e., remanence, coercivity, and energy product), but slightly lower compressive strength of approximately 845 kgf/cm 2 .

“…It has been shown that the magnetic properties of LENS fabricated AlNiCo PMs are similar or better to the counterparts manufactured using more conventional casting or sintering. Here, the achieved remanence and coercivity are equal to 0.9T and -161.5kA/m [31], [34]. When it comes to MnAlC PMs, the initial results have shown that manufacture of solid material samples is possible.…”

“…Traditionally, PB-AM methods are using gas-or plasma atomized powders [7,37] made from pre-alloyed material. But in cases when non-equilibrium material microstructure is desirable (like with BMG, HEA and some other materials), blends of elemental powders can be used [28,30,31,[38][39][40].…”

“…; thermal conductivity of 180-200 W/(m • K) (as in Al), in single crystals up to 470 W/ (m • K); working temperaturemore than 1350°C (as in heatresistant steels); melting/decomposing point is 2830°C; resistance in the oxidizing and reducing environment is higher than that of Ti [89]. PB-AM technologies demonstrate significant potential in manufacturing of composite materials both from the blended powders and pre-agglomerated powders where each grain already contains multiple materials sintered together [28,38,39,90].…”

The current paper is devoted to classification of powder-bed additive manufacturing (PB-AM) techniques and description of specific features, advantages and limitation of different PB-AM techniques in aerospace applications. The common principle of “powder-bed” means that the used feedstock material is a powder, which forms “bed-like” platform of homogeneous layer that is fused according to cross-section of the manufactured object. After that, a new powder layer is distributed with the same thickness and the “printing” process continues. This approach is used in selective laser sintering/melting process, electron beam melting, and binder jetting printing. Additionally, relevant issues related to powder raw materials (metals, ceramics, multi-material composites, etc.) and their impact on the properties of as-manufactured components are discussed. Special attention is paid to discussion on additive manufacturing (AM) of aerospace critical parts made of Titanium alloys, Nickel-based superalloys, metal matrix composites (MMCs), ceramic matrix composites (CMCs) and high entropy alloys. Additional discussion is related to the quality control of the PB-AM materials, and to the prospects of new approaches in material development for PB-AM aiming at aerospace applications.
