4D synchrotron X-ray tomographic study of the influence of transverse magnetic field on iron intermetallic compounds precipitation behavior during solidification of Al-Si-Fe alloy

Jiawei Cao et al.

Summary: The presence of iron element in aluminum alloy leads to the formation of hard and brittle iron intermetallic compounds (IMCs), which can deteriorate the mechanical properties of the material. The study found that the precipitation behavior and growth dynamics of IMCs were significantly affected by the applied transverse magnetic field (TMF). TMF caused the IMCs to form only on the periphery of the sample and affected their growth rate and formation mechanism.

Revealing the influence of Fe on Fe-rich phases formation and mechanical properties of cast Al-Mg-Mn-Fe alloys

Yuliang Zhao et al.

Summary: Recycled Al-Mg-Mn-Fe alloys with different Fe levels were successfully prepared by squeeze casting. The relationship between microstructural evolution and mechanical properties was studied using various techniques. The results showed that Fe additions increased the yield strength and ultimate tensile strength of the alloys. The morphological evolution of the alloys from individual Chinese-script to interconnected plate-like shape was observed. In-situ radiography revealed the facet growth behavior of Al6(FeMn) phases during solidification. The applied pressure was found to refine the grains and reduce the volume fraction of pores, contributing to the improvement of strength and elongation.

Dong-Fu Song et al.

Summary: The evolution of 3D Fe-rich phases in Al-7.0Si-1.2Fe alloys with different Mn contents was characterized using synchrotron X-ray computed tomography. The addition of Mn changed the morphology of Fe-rich phase and reduced its volume fraction, while high Mn content led to decreased ductility of the alloy.

Making sustainable aluminum by recycling scrap: The science of dirty alloys

Dierk Raabe et al.

Summary: Aluminum has both positive and negative impacts on sustainability. Recycling aluminum can improve sustainability, while extracting it from ores is energy-intensive. The amount of recyclable aluminum is expected to double by 2050, offering an opportunity for a circular economy. However, the presence of elemental contamination in post-consumer scrap poses challenges for alloy design.

Strong and ductile recycled Al-7Si-3Cu-1Fe alloy: Controlling the morphology of quasicrystal approximant alpha-phase by Mn and V addition

Tales Ferreira et al.

Summary: This paper investigates the microstructure control of recycled Al-7Si-3Cu alloy through the addition of Mn and V, resulting in the formation of a microstructure containing nano-submicron size quasicrystal approximant alpha-phase, leading to improved strength and ductility at temperatures up to 250 degrees C. Secondary processing techniques such as rotary swaging and Si globulization treatment further enhance the alloy's tensile properties at different temperatures, contributing to the valuable applications of recycling alloys without the addition of primary Al.

Fe-bearing phase formation, microstructure evolution, and mechanical properties of Al-Mg-Si-Fe alloy fabricated by the twin-roll casting process

Xu Liu et al.

Summary: The formation of Fe-bearing phases in Al-0.53Mg-0.69Si-0.14Fe alloy under different casting processes was studied in this work. The promotion of the peritectic reaction in the TRC process led to the formation of pi-AlFeMgSi phase, while the DC process resulted in the formation of beta-AlFeSi phase. After homogenization treatment, the TRC sample exhibited higher yield strength than the DC sample due to the lower dissolution temperature of pi-AlFeMgSi phase.

Rong Qin et al.

Summary: The study explores the effects of V element addition on the microstructures, mechanical properties, and thermal conductivity of Al-8Si-0.1Cu-0.6Mg-0.7Fe hypoeutectic alloy in gravity die casting. It was found that V modification can influence the size of Fe-rich phases in the alloy, subsequently impacting the mechanical properties and thermal conductivity. Optimal levels of mechanical properties and thermal conductivity were achieved when the content of V element was 0.6%, as excessive V addition led to poor alloy properties.

Growth dynamics of faceted Al13Fe4 intermetallic revealed by high-speed synchrotron X-ray quantification

Zihan Song et al.

Summary: High-speed synchrotron tomography was used to investigate the nucleation and growth dynamics of Al13Fe4 intermetallic during solidification of an Al-5wt%Fe alloy, providing new insights into its formation process. The majority of Al13Fe4 intermetallics nucleated near the surface oxide of the specimen and grew into various shapes, possibly influenced by the crystal structure and twinning susceptibility of the compound. Hole-like defects filled with aluminium melt were observed within the intermetallics, and an oriented particle attachment mechanism was proposed to explain the formation of the Al13Fe4 intermetallic, calling for further experiments and simulations to confirm.

Nucleation and growth of Fe-rich phases in Al-5Ti-1B modified Al-Fe alloys investigated using synchrotron X-ray imaging and electron microscopy

Yuliang Zhao et al.

Summary: The study investigated the nucleation and growth mechanisms of Fe-rich phases in Al-5Ti-1B-modified Al-2Fe alloys during solidification using synchrotron X-ray imaging and electron microscopy. It was found that Al-5Ti-1B grain refiner and applied pressure reduced the size and number of primary Al3Fe phases, while promoting the formation of eutectic Al6Fe phases in the alloy. The three-dimensional morphology of Fe-rich phases was altered from rod-like to branched plate-like by Al-5Ti-1B, with a decrease in thickness and size attributed to various factors including Ti-containing solutes and Al3Fe twins.
