The microstructural characteristics of the high pressure die casting (HPDC) AlSiMgMnCu alloys in skin layer, segregation band and central zone were investigated three dimensions by serial block-face scanning electron microscopy (SBFSEM). results present that volume fractions α-Al15(Fe, Mn)3Si (α-Fe phase), β-Mg2Si (β phase) Q-Al5Cu2Mg8Si6 (Q layer are higher than those zone. sizes θ-Al2Cu phase (θ lower In preferential growth orientation α-Fe with plate-like morphology is parallel to heat...
Herein, Al – 8Si 0.5Mn 0.5 Mg 0.2Cu x Zn alloys ( = 0, 1, 2, and 3 wt%) are produced by a vacuum‐assisted high‐pressure die casting process. The effects of addition on the surface layer thickness segregation band, number density externally solidified crystals (ESCs), mechanical properties systemically investigated. As content increases, size ESCs increase. morphology eutectic Si phase could be modified Zn. In addition, microstructural heterogeneity indicates that band zone increase with...
In this study, AlSiMgMnCu alloys with different Cu and Mg contents were processed by the high pressure die casting (HPDC) technics. The phase formation their microstructure evolution are quantitatively studied serial block-face scanning electron microscopy (SBFSEM) at nano-scale in three-dimensions (3D). Through analysis of 3D microstructure, effects spatial distribution, volume fractions morphology intermetallic phases on mechanical properties systematically discussed. It is found that,...

A method to calculate solute solution in Al alloy castings, based on the serial block-face scanning electron microscopy (SBFSEM) measurement at nano-scale, was proposed. For high vacuum die casting (HVDC) Al-10Si-0.4MgMn-0.6Cu alloy, it reveals that fractions of Si, Mg and Cu matrix reaches about 0.39 wt.%, 0.15 0.10 respectively, under as-cast condition. After heat treated via T5 process, larger nano-scale precipitation phases with low density non-uniform distribution were formed α-Al...
