Abstract Scope AlCuLi based alloys are high strength, low density alloys which have been of high interest for bulk applications to the aircraft and automotive industries when prepared by ingot casting methods. Rapidly solidified AlCuLi alloys present a sparsely studied system, which could find use in other applications, such as MEMS components. The high solidification rate leads to formation of a fine grained to amorphous microstructure and formation of highly non-equilibrium crystalline and quasicrystalline phases. Systems where crystallite size is comparable to size of strengthening and constituent phases can be of interest for potential applications, but also studying of fundamental processes of materials science such as and phase transformations. When studied by in-situ annealing and phase mapping in TEM these processes are observed in real time with very high resolution.
