Abstract Laser Powder Bed Fusion (L-PBF) provides great advantages in creating supersaturated solid solutions due to its intrinsic ultrafast cooling and high solidification rate …
We study the precipitation behavior of two L1 2-strengthened alloys with Mg and Y additions: ultralow-Sc, Si-free, Al-1Mg-0.09 Zr-0.007 Sc-0.006 Er-0.02 Y-0.01 Si, and low-Sc, Si-added …
The unprecedented increase in component design space has led to significant focus on fusion-based additive manufacturing (AM) technologies. The new design possibilities …
An attractive approach to mitigate hydrogen embrittlement (HE) is to use nano-sized particles to immobilize hydrogen. However, the atomic scale relationship between different …
Abstract The aluminum-zirconium (Al-Zr) alloys are of interest because of their superior thermal stability and good electrical conuctivity, but their main drawback is their rather low …
The microstructures of alloys created via Additive Manufacturing (AM) can vary substantially from those present in cast or wrought products, due to the very rapid solidification associated …
