Abstract Scope |
In this study, the laser-foil-printing (LFP) process has been successfully used to fabricate the AZ31B magnesium (Mg) alloy with high strength and ductility in a risk-free way. Compared to the laser powder bed fusion (L-PBF) processes, the LFP process enhances resistance to oxidation and mitigates the potential explosive risks associated with Mg by using foil as the feedstock material. The microstructure, hardness, and tensile properties of the LFP-fabricated AZ31B parts (approximately 99.9% relative density) were characterized. The tensile results indicated that the ultimate tensile strength (UTS) and elongation (EL) exhibit similarity and isotropy along the laser scanning and building directions, in which possesses superior mechanical properties than other laser additive manufacturing (LAM) processes. Through electron backscatter diffraction (EBSD) technique, the grain size of LFP parts was finer compared to LAM-fabricted parts, due to its higher cooling rate. |
