| Abstract Scope |
The Powder Bed Fusion (PBF) process is used for the additive manufacturing (AM) of metal parts and is capable of producing a wide variety of complex and intricate components. For AlSi10Mg, thermal post-processing is crucial to achieve the full range of material properties. This work focuses on the effects of thermal post-processing on AlSi10Mg microstructural evolution. AM AlSi10Mg coupons were fabricated by PBF, then were thermally treated using a conventional approach (with a Solution Heat Treatment (SHT)), and an alternative approach adapted for AM (without a SHT). Micro-tensile specimens were cut by EDM, and ductility and tensile strength were measured, with the alternative annealing approach resulting in superior tensile strength. Microstructural differences are correlated to tradeoffs in mechanical properties and deformation mechanisms. |
