Abstract Scope |
The aerospace industry is an enticing field for the deployment of additive manufactured (AM) parts. This brings the need for the development of AM techniques in materials relevant for this industry, such as Ni, Al and Ti based alloys. A205, a Cu alloyed Al alloy with desirable mechanical properties and a refined grain structure. Particularly, when produced through selective laser melting, A205 presents micron sized equiaxed grains. Before service, these alloys must go through a careful set a heat treatments to produce an intricate precipitate structure. The schedule for the heat treatment in cast alloys is known, but may be optimized for the unique SLM as-built structure. In this work we present a set of in-situ XRD experiments to track phase transformations during homogenization and aging and in A205 alloys produced through SLM. The kinetics of solidification second phase dissolution and precipitate formation are tracked for several temperatures. |
