Special Issue Information

Dear Colleagues,

We are pleased to announce a Special Issue focused on the latest advancements in the Additive Manufacturing (AM) of Metallic Materials. This issue aims to explore cutting-edge research in various areas, including the Selective Laser Melting (SLM) process, porous structures, tissue engineering, functional biomaterials, Powder Metallurgy (PM), innovation in integrated techniques, lattice and scaffolds design and simulation, and Wire Arc Additive Manufacturing (WAAM). AM has revolutionized traditional manufacturing processes, enabling the production of complex geometries and customized designs. Laser Powder Bed Fusion (LPBF) techniques offer high precision and versatility, while Functionally Graded Materials provide enhanced material properties. Porous Structures play a crucial role in tissue engineering applications, facilitating cell growth and bone regeneration.

This Special Issue will showcase research on metallic complex shaped, exploring their unique characteristics and applications in different fields. PM techniques will also be featured and combined with AM for potential in manufacturing advanced materials. Lastly, recent technologies like WAAM and Binder Jetting (BJ) will demonstrate advancements on a large scale and in the mass production of metal fabrications. We invite researchers, scientists, and engineers to contribute original research papers and reviews to this Special Issue. Submissions should address significant processes, advancements, fabrications, and applications in the Additive Manufacturing of Metallic Materials.

In order to improve the performance of 17-4PH under wear conditions (e.g., gears, etc.) and reduce the cost of metal additive manufacturing, TiC needs to be added to 17-4PH to improve its wear resistance. Micron-sized TiC-reinforced 17-4PH stainless steel composites with different contents (0–15 wt%) have been prepared by fused filament fabrication 3D printing for the first time. The effects of TiC content on the structure and properties of composites were studied by XRD, SEM, and sliding wear. The obtained results show that the microstructure of TiC-reinforced 17-4PH stainless steel composites mainly consists of austenite. With the increase in TiC content, the grain size is obviously refined, and the average grain size decreases from 65.58 μm to 19.41 μm. The relative densities of the composites are maintained above 95% with the addition of TiC. The interfaces between TiC particles and the 17-4PH matrix are metallurgical bonds. The hardness of the composites increases and then decreases with increasing TiC content, and the maximum hardness (434 HV) is obtained after adding 10 wt.% of TiC content. The wear rate of the composites was reduced from 2.191 × 10−5 mm3 /(N‧m) to 0.509 × 10−5 mm3 /(N‧m), which is a 3.3-fold increase in wear resistance. The COF value declines with the addition of TiC. The reasons for the significant improvement in the composites’ performance are fine grain strengthening, solid solution strengthening, and second phase strengthening. The wear mechanisms are mainly abrasive and adhesive wear. Compared to the 10 wt% TiC composites, the 15 wt% TiC composites show limited improvement in wear resistance due to more microcracks and TiC agglomeration. Full article
