Laser Powder Bed Fusion of CuSn10: A Review

Abstract

This review examines the current state of CuSn10 alloy manufacturing using Laser Powder Bed Fusion. Through a systematic literature search, 32 articles on LPBF-processed CuSn10 are identified and evaluated. This provides an overview of processing parameters, microstructures, mechanical properties, corrosion behavior, the effect of heat treatments, and multimaterial connections. The results show that various parameter configurations in LPBF production can achieve high densities even at lower laser powers. The resulting alloy exhibits a fine anisotropic microstructure and inherent residual stresses, which can be mitigated through thermal post-processing. The mechanical and technological properties of LPBF-fabricated material exceed those of conventionally produced material and can be adjusted through subsequent heat treatments. Significant variations in elongation are observed, which could be attributed to inconsistencies in the geometry of the tensile specimens. The review emphasizes the need for standardized test geometries and consistent reporting of specimen orientation during manufacturing to improve reproducibility and comparability. Future research should focus on systematically investigating the relationships between processing parameters and material properties, as well as exploring anisotropy and behavior under cyclic loading. Finally, future developments are assessed based on current trends.
