“…The properties, particular the ductility, of cast Al-Si alloys have a strong correlation with the amount of porosity present on the facture surface [35,36]. In particular, it is the projected area of the micro-voids on the fracture surface, rather than the volumetric porosity as measured by the bulk density, that is most important [37,38]. Since SLM can be considered as repeated micro-scaled casting events, it is not surprising that the same effects appear to be occurring here.…”

Al-12Si components were manufactured by Selective Laser Melting (SLM) using three different atmospheres: argon, nitrogen and helium. The atmosphere type did not affect the part's density or hardness and all components reached near full relative density (>97%). The mechanical properties of the components produced in Ar and N 2 were superior to those in He, especially the ductility, which has been attributed to the formation of pore clusters in the microstructure. The mechanical properties in SLM-produced components are superior to those produced using conventional method.

“…In the current study, lower mechanical properties of the specimens cast with lower cooling rate (higher SDAS) were the consequence of inhomogeneous deformation and higher strain distribution around larger eutectic Si particles and Fe-rich intermetallics. The decrease of mechanical properties with higher SDAS, and larger eutectic Si and Ferich β-intermetallics has been reported in the different studies in literature [6,[26][27][28].…”

“…2a is similar to the related aluminium alloys after T6 heat treatment. 13 To verify this, a microstructural observation of as cast die cast samples was carried out following T6 treatment (solution temperature at 773 K for 2 h and aging at 443 K for 10 h). Figure 2c displays the optical micrograph for the T6 die cast sample.…”

Die cast aluminium alloys, including automotive parts, are generally understood to suffer some degradation of their mechanical properties over time due to corrosion, specifically when exposed to water and sea breeze (salt air). However, in this study, it is shown that in the absence of a corrosive environment, the mechanical properties of die cast aluminium alloys actually increase over a 10 year period due to natural aging. The increment in the mechanical properties is mainly attributed to precipitation hardening brought about by h0 phase particles. It also appears that any significant change in microstructure affects the mechanical properties, e.g. the change of the needle-like eutectic Si to a spherical form and the joining of discrete a-Al phases to make larger grains. The driving force for the microstructural changes upon natural aging is related to the residual stress in the die cast sample accumulated by high casting pressure and rapid cooling rate during injection process.
