| Abstract Scope |
The utilization of additive manufacturing allows for a higher degree of freedom as it enables an adjustment of microstructure and properties. Due to high damage tolerance, austenitic steels are promising candidates for application in additive manufacturing with regard to unavoidable process-induced defects, such as pores. The addition of Al in those alloys can yield several advantages, e.g. the reduction of density, and therefore a higher potential for lightweight design. In the present study, a Cr-Mn-Ni steel with the addition of 4.5Al was processed by laser-based powder bed fusion of metals (PBF-LB/M) at different substrate plate temperatures. Based on varying cooling rates, different phase constitutions are realized ranging from a single phase to a duplex microstructure. The implementation of different substrate temperatures will not only influence the solidification of microstructure, but also the resulting properties. With respect to different microstructures, quasi-static mechanical tests and corrosion experiments were conducted. |
