How Slight Solidification Rate Variations within Cast Plate Affect Mechanical Response: A Study on As-Cast A356 Alloy with Cu Additions

Figure 3

Optical micrographs and SDAS measurements as function of Cu content and specimen cutting position. Micrographs depict the microstructure of the Cu-free alloy (a)–(c), the 0.5% Cu alloy (d)–(f), and the 1% Cu alloy (g)–(i) with SDAS ranging from 30 up to ∼40 µm.
