| Abstract Scope |
Maraging steels are notable for their low carbon content and exceptional combination of ultra-high strength, ductility, machinability, dimensional stability, and fracture toughness. They hold promise for use as spring steel in sectors like automotive and food. Additive manufacturing (AM) offers a more cost-efficient method for creating complex geometries with precise control over microstructure, mechanical properties, and corrosion resistance, all within shorter production times. Mechanical properties are significantly affected by the presence of retained austenite (RA) and reversed austenite. Although considerable research has focused on the relationships between input parameters and output parameters, the specific effects of RA, reversed austenite, and heat treatment on mechanical properties remain underexplored. This study presents initial findings on the additive manufacturing of maraging steels of 1.2709 grade for lightweight applications. The mechanical properties of the samples are analyzed, and the impact of heat treatment on RA content is also discussed and correlated. |
