“…The samples were manufactured from the blend of powders at Sports Tech Research Centre, Mid Sweden University in the ARCAM EBM A2 machine (by ARCAM EBM, a GE Additive Company, Göteborg, Sweden) modified for manufacturing of test samples from small powder batches. Modified setup uses small working area with the base plate diameter 82 mm and small powder container connected to the raking mechanism (see [32] for details). Vertical arrangement of the powder container allows for working with small amounts of powder (down to 100 cm 3 ).…”

High Entropy Alloys (HEAs) is a novel promising class of multi-component materials which may demonstrate superior mechanical properties useful for high-temperature applications. Despite the high potential of HEAs, their production is complicated, using pre-alloyed powders in powder metallurgy route. This significantly complicates development and implementation of refractory BCC solid solution based HEAs. The present paper reports on experiments aiming at production of Al0.5CrMoNbTa0.5 multi-principle alloy using powder bed beam based additive manufacturing. Samples were manufactured using Selective Electron Beam Melting (SEBM) additive manufacturing technique from a blend of elemental powders aiming at achieving microstructure with high configurational entropy. Though it was not possible to achieve completely homogeneous microstructure, the as-printed material was composed of the zones with two multi-component solid solutions, which differed only by Al content confirming in situ alloying. The process parameters optimization was not carried out and the as-print material contained a notable amount of residual porosity. It was possible to reach lower porosity level using heat treatment at 1300 °C for 24 hours, however undesirable alloy composition changes took place. The main conclusion is that the production of the Al0.5CrMoNbTa0.5 multi-principle alloy from elemental powder blends using SEBM technique is achievable, but the process parameter optimization rather than post-process heat treatment should be performed to reduce the porosity of samples.

“…There were no found any reported data where EBM has been used in hybrid AM, as it is still seemed too complicated to print on some other substrate, except standard building platform, specific for each printed material. However PB-EBM using blended powders, including addition of ceramic nano-powder into metallic powder, can be the way for production of composite-like hybrid multi-materials [13,50,51].…”

“…But having of combination materials from different classes, for example, organic-inorganic [1]; bio-based-rubber [2]; metal-polymer [3]; steel-glass [4,5] the term "hybrid" became more often used to declare nature of the material type. To achieve unique properties or properties combinations researchers pay attention to hybrid materials design: for lightweight ceramic materials [6], lightweight and high-temperature resistant materials [7,8], metalceramic lightweight hybrid materials [9], hybrid polymer matrix composites [10,11], and hybrid metal-based composites [12][13][14]. The current extremely growing development of additive manufacturing processes allows starting implementing of combining different AM approaches together with traditional manufacturing to obtain hybrid materials with 3-dimensional sophisticated design.…”

Hybrid additive manufacturing is a relatively modern trend in the integration of different additive manufacturing techniques in the traditional manufacturing production chain. Here the AM-technique is used for producing a part on another substrate part, that is manufactured by traditional manufacturing like casting or milling. Such beneficial combination of additive and traditional manufacturing helps to overcome well-known issues, like limited maximum build size, low production rate, insufficient accuracy, and surface roughness. The current paper is devoted to the classification of different approaches in the hybrid additive manufacturing of steel components. Additional discussion is related to the benefits of Powder Bed Fusion (PBF) and Direct Energy Deposition (DED) approaches for hybrid additive manufacturing of steel components.* e-mail: vvp@technion.ac.il Rev. 7, 6 (2020) This is an Open Access article distributed under the terms of the Creative Commons Attribution License (https://creativecommons.org/licenses/by/4.0), which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited.
