Yep, it’s all about focusing on the Applications – and in some of them, you may want to swap Silicon with Cerium.
Seriously.
We just listed on VALIMET Literature page a work by Holden Hyer, David Weiss and other co-authors:
“High strength aluminum-cerium alloy processed by laser powder bed fusion”
DOI: https://lnkd.in/gEM852WZ
As we explained before, we are particularly keen on collaborations among various organizations. In this case, University of Central Florida, University of New Hampshire, Eck Industries, Inc. and U.S. Army DEVCOM Army Research Laboratory came together for an interesting contribution to the development of Aluminum Alloys for Additive Manufacturing.
They CALPHAD phase-diagram calculations and Scheil solidification modeling to pre-screen the alloy for LPBF processability, rather than relying on trial-and-error.
It turns out that, for resistance to higher temperatures, aging, thicker walls, and as-printed conditions, Cerium-containing alloys can outperform AlSi10Mg.
The fact that Ce-based inter-metallics do not spheroidize or dissolve during repeated thermal cycling, unlike Si, has an interesting implication: this property can make Al-Ce-Mg structurally superior for Aerospace, Propulsion, Thermal Management, and in general Defense parts.
