There are several facets of aluminum when it comes to sustainability. While it helps to save
fuel due to its low density, producing it from ores is very energy-intensive. Recycling it shifts …

In this paper, the Fe-rich phases in and their detrimental effect on aluminum alloys are
summarized. The existence of brittle platelet β-Fe-rich phases lowers the mechanical …

Abstract In secondary Al-Si based alloys, microalloying with Mn and Cr can modify harmful
platelet-type Al x Fe y Si z intermetallic phases to less detrimental α-Al x (Fe, Mn, Cr) y Si z …

The thermomechanical properties of particle-reinforced metal matrix composites (MMCs) are
attractive for many structural applications, but fabrication of MMC parts with conventional …

Iron is the most common and detrimental impurity in aluminum casting alloys and has long
been associated with an increase in casting defects. While the negative effects of iron are …

A theory is presented to explain the mechanism of formation of the eutectic phases in Al–Si
hypoeutectic alloys. Results include optical, scanning and transmission electron microscopy …

Excess impurity Fe will form various intermetallic compounds in Al-based alloys, such as α-
Al 8 Fe 2 Si and β-Al 5 FeSi, which greatly reduce the elongation of alloys. Therefore, Fe …

Multiphase solidification in multicomponent alloys is pertinent to many commercial materials
and industrial processes, while also raising challenging questions from a fundamental point …

Abstract Secondary Al–Si alloys Al7. 1Si (1.5-x Mn) Fe (x Mn) Mn with x Mn= 0, 0.3, 0.375,
0.6, 0.75 at.% have been solidified with different cooling rates: 0.05 K/s, 1.4 K/s, 11.4 K/s and …

This study focuses on primary impurities, called intermetallics, in the microstructure of Al-Si-
X alloys, their formation, effects and treatments to eliminate or ameliorate their deleterious …
