摘要
An Al84Si6Cu3Mg7 alloy was produced by melt-spun and conventional casting and characterized using X-Ray Diffractometry (XRD), Scanning Electron Microscopy (SEM), High Resolution Transmission Electron Microscopy (HRTEM) and microhardness techniques. Meltspun minimizes second phase formation and increases the alloying content in solid solution. Q phase (Al5Cu2Mg8Si6;) nanocrystallites (5 nm) were observed for melt-spun alloys. The high alloying content in solid solution and the small alpha-Al grain size (300 nm) for ribbons lead to a hardness improvement of about 2.4 times greater than that of conventionally cast alloys.
