Summary: In this study, a trace alloying method was used to fabricate strong and ductile CuCrZr alloys using laser powder bed fusion (L-PBF). The laser absorptivity and flowability of the CuCrZr powders were enhanced by trace Zr alloying, resulting in the production of dense L-PBF builds. Subsequent multisteps including hot isostatic pressing, solution treatment, and aging resulted in the precipitation of submicron Cr particles, leading to a CuCrZr alloy with high strength and ductility. The findings suggest that combining L-PBF and traditional metallurgical processes can be used to design and manufacture high-performance Cu alloys for various applications.

Summary: This study demonstrated the manufacturing feasibility and structural evolution of MXene-reinforced MMCs prepared by L-PBF. The novel MXene/Al composite co-reinforced with MXene sheets, TiC nanorods, and alpha-Al2O3 particles was successfully synthesized, providing new insights into expanding the applications of MXene and fabricating high-performance MMCs.

Summary: This study experimentally determined the impacts of severe oxidation on the characteristics of 316L stainless steel powder and the melting behaviors in laser powder bed fusion (L-PBF). The results showed that powder oxidation can improve the L-PBF processability by enhancing the uniformity of powder spreading and the stability of laser fusion. A ceramic layer-coated SS alloy was synthesized by processing severely oxidized powders, and its mechanical strength was similar to that processed using virgin powders.

Summary: This study suggests the use of mechanical ball milling to improve the flowability and spreadability of gas-atomized (GA) Ti-48Al-2Cr-2Nb powder in powder bed fusion additive manufacturing. The deformation mechanism of the GA powder differs depending on the ball milling media. Al2O3 ball milling mainly causes surface grinding, while WC ball milling leads to pulverization due to higher impact force. After Al2O3 and WC ball milling, the flowability of the GA powder under dynamic conditions improves due to decreased cohesive force and the packing density increases due to rapid energy dissipation, minimized wall effect, and void filling effect.

Summary: Powder flowability plays a crucial role in additive manufacturing, influenced by particle size distribution, particle morphology, and surface features. Experimental evaluation and numerical simulations on Inconel 718 alloy powders revealed that PREP powder exhibited the best flowability due to high particle sphericity and thin surface oxide film. Control of environmental factors during handling can lead to a natural advantage of PREP over GA and PA in terms of flowability.
