Evidence of disruption of Si-rich microstructure in engineering-lightweight Al-12.2at.%Si alloy melt above liquidus temperature.

The exploration of microstructures in high temperature alloy melts is important for manufacturing of metallic components but extremely challenging. Here, we report experimental evidence of the disruption of Si-rich microstructure in engineering-lightweight Al-12.2at.

Formation of strength platform in cast Al-Si-Mg-Cu alloys.

Over the past several decades, it was generally believed that the strength of the industrially widely used cast Al-Si-Mg-Cu alloys enhanced monotonously with increasing Cu content. However, in this study using cast Al9Si0.5MgxCu (x = 0,0.
