| Abstract Scope |
The utilization of cored wire is of significant interest in both wire and powder-based Additive Manufacturing (AM) processes, providing the ability to undertake in-situ alloying additions and rapidly assess the influence of composition on properties.
This study investigates the influence of varying molybdenum levels on the mechanical and electrochemical behaviour of 316L built by Laser Powder Bed Fusion (L-PBF). The cored wire was processed using Ultrasonic Atomisation (UA) to manufacture powders with varying levels of molybdenum built into suitable test samples using L-PBF. Mechanical testing included tensile strength, hardness, and density, while corrosion resistance was assessed through changes in corrosion potential, linear polarisation resistance and pitting potential.
This research demonstrates the ability to optimise alloy compositions, facilitating the development of tailored 316L steels for AM with desired mechanical and corrosion properties. This approach will be extended for use in new alloys (e.g. high entropy alloys). |
