| Abstract Scope |
Recently, we have developed a series of Al-Cr-Mn-Co-Zr alloys that exhibit a nano-composite FCC Al matrix plus QC dispersoid microstructure in gas-atomized powders. Upon consolidation, the microstructure of the powders is retained in the bulk material. This material exhibits promising mechanical properties as well as pitting corrosion resistance compared to conventional Al alloys. These alloys are being explored for use in a variety of additive manufacturing (AM) techniques, including friction stir additive manufacturing (FSAM). Here, we present preliminary observations on the impact of microstructure on the hardness and corrosion behavior of the FSAM samples through a combination of microhardness testing, scanning and transmission electron microscopy, focused ion-beam milling and polarization techniques. |
