“…Despite a non-uniform dispersion of TiB 2 within the Al matrix, slight grain refinement was achieved in the samples containing 4 wt% TiB 2 . Wen et al [115] also reported the same trend in their studies on 2024Al/TiB 2 composites produced via DED. In another study, Li et al [103] evaluated the effect of nano-TiB 2 on the microstructural evolution of the AlSi10Mg alloy produced via the LPBF process.…”

“…AMCs reinforced by nanomaterials, the presence of nanoscale reinforcements results in the formation of ultrafine grains. Wen et al [115] used nano-TiB 2 particles to strengthen 2024Al alloy produced via the DED process. In their 2024Al-3 wt% TiB 2 nanocomposites, the high tensile strength of 284 MPa and excellent ductility of 18.7% were achieved, which were much higher than those of 2024Al alloys produced by casting.…”

Nowadays, as an emerging technology, additive manufacturing (AM) has received numerous attentions from researchers around the world. The method comprises layer-by-layer manufacturing of products according to the 3D CAD models of the objects. Among other things, AM is capable of producing metal matrix composites (MMCs). Hence, plenty of works in the literature are dedicated to developing different types of MMCs through AM processes. Hence, this paper provides a comprehensive overview on the latest research that has been carried out on the development of the powder-based AM manufactured MMCs from a scientific and technological viewpoint, aimed at highlighting the opportunities and challenges of this innovative manufacturing process. For instance, it is documented that AM is not only able to resolve the reinforcement/matrix bonding issues usually faced with during conventional manufacturing of MMCs, but also it is capable of producing functionally graded composites and geometrically complex objects. Furthermore, it provides the opportunity for a uniform distribution of the reinforcing phase in the metallic matrix and is able to produce composites using refractory metals thanks to the local heat source employed in the method. Despite the aforementioned advantages, there are still some challenges needing more attention from the researchers. Rapid cooling nature of the process, significantly different coefficient of expansion of the matrix and reinforcement, processability, and the lack of suitable parameters and standards for the production of defect-free AM MMCs seem to be among the most important issues to deal with in future works.

“…The nucleation of new grains at the solidification frontier generally required numerous nucleation sites and an energetically favorable condition. Usually, the undercooling at solidification front was able to provide an energetically favorable condition [ 39 ]. After incorporating RGO, the undercooling at the interface was significantly enhanced owing to the high thermal conductivity of RGO.…”

Zinc (Zn) possesses desirable degradability and favorable biocompatibility, thus being recognized as a promising bone implant material. Nevertheless, the insufficient mechanical performance limits its further clinical application. In this study, reduced graphene oxide (RGO) was used as reinforcement in Zn scaffold fabricated via laser additive manufacturing. Results showed that the homogeneously dispersed RGO simultaneously enhanced the strength and ductility of Zn scaffold. On one hand, the enhanced strength was ascribed to (i) the grain refinement caused by the pinning effect of RGO, (ii) the efficient load shift due to the huge specific surface area of RGO and the favorable interface bonding between RGO and Zn matrix, and (iii) the Orowan strengthening by the homogeneously distributed RGO. On the other hand, the improved ductility was owing to the RGO-induced random orientation of grain with texture index reducing from 20.5 to 7.3, which activated more slip systems and provided more space to accommodate dislocation. Furthermore, the cell test confirmed that RGO promoted cell growth and differentiation. This study demonstrated the great potential of RGO in tailoring the mechanical performance and cell behavior of Zn scaffold for bone repair.

“…pct TiB 2 powder particles with the base alloy, and an order of magnitude decrease in the grain size was reported with the TiB 2 additions, from 23 lm to 2.5 lm. Wen et al [127] added 3 wt pct TiB 2 to 2024 in a laser solid forming process and achieved equiaxed microstructure having a grain size range of 20-35 lm with increased mechanical performance of components compared to long columnar grains with width ranging from 60 lm to 1.6 mm in 2024 without the grain refiner. Most recently, LaB 6 has also been shown to be an effective nucleant particle during L-PBF of Al10SiMg, as shown in Figures 5(c) and (d).…”
