Secondary Al-Si-Mg High-pressure Die Casting Alloys with Enhanced Ductility
Dominik Bösch,Dominik Bösch,Stefan Pogatscher,Marc Hummel,Werner Fragner,Peter J. Uggowitzer,Mathias Göken,Heinz Werner Höppel +7 more
TL;DR: In this article, the effect of manganese additions at high cooling rates on microstructure, mechanical properties, and on the dominating fracture mechanisms of alloy AlSi10Mg with an elevated iron concentration was investigated.

Pore Formation and Melt Pool Analysis of Laser Welded Al-Cu Joints using Synchrotron Radiation
TL;DR: In this article , high-speed images show a fluctuating copper flow towards the keyhole and a material mixing over the entire aluminium melt pool depth. And pore formation in front and bottom of the key hole is observed, and the movement of the bubbles in the melt pool can be tracked until solidification at the material transition.

Formation of Die Soldering and the Influence of Alloying Elements on the Intermetallic Interface.
TL;DR: In this article, the formation of a scattered granular intermetallic phase formed at the interface between steel and Al-alloy after immersion into the melt for a duration of 6 min at 710 °C, and the presence of the irregular needle-shaped β-Al5FeSi phase and the surrounding alloy was responsible for the bond between the two components.
