Meeting 2020 TMS Annual Meeting & Exhibition
Symposium Additive Manufacturing: Materials Design and Alloy Development II
Presentation Title A20X and AlSi10Mg Aluminium Alloys: A Comparison
Author(s) Richard Selo, Ian Maskery, Ian Ashcroft, Christopher Tuck
On-Site Speaker (Planned) Richard Selo
Abstract Scope This work describes the development and characterisation of a high strength aluminium copper alloy previously known to have poor processability with Laser Powder Bed Fusion (LPBF). A20X, a version of A201 casting alloy with modified composition to reduce hot cracking has been studied. Process parameter optimisation is investigated to achieve low porosity (<0.05%). This high-strength alloy is compared to AlSi10Mg, the go-to aluminium alloy for LPBF, in terms of microstructure and hardness and its advantages and inconvenient are discussed.
