Abstract Scope |
Quasicrystal-reinforced aluminum metal matrix composites exhibit combinations of properties that are attractive for metal additive manufacturing (MAM). It is challenging to evaluate such systems due to difficulties in modeling solidification and microstructural evolution. Here, laser glazing was used as a cost-effective method to evaluate the potential of a powder-processed Al-Cu-Fe-Cr alloy for MAM. Since the quasicrystal reinforcement phase is inherently metastable, it is important to understand the thermal stability of this phase. In situ transmission electron microscopy (TEM) heating studies can allow us to observe the phase transformation of a specific area of interest dynamically. Here we also report in situ TEM heating studies on focused ion beam (FIB)-cut samples of single laser tracks of the same alloy. |
