| Abstract Scope |
Grade 300 maraging steels are the most widely used maraging steels in additive manufacturing (AM) and have shown a different resultant microstructure, as compared to the one obtained by conventional processing. Most AM processes used to synthesize metallic materials exhibit a rapid cooling rate during and after solidification (typically up to 106 K/s in laser powder bed fusion-LPBF). Consequently, the microstructure of as-LPBF-produced maraging 300 steels consist of martensite without any precipitates, however, it might contain a significant amount of retained austenite. The present work shows how the difference in chemical homogeneity and phase distribution of AM produced maraging 300 steel affect the microstructural evolution during ageing treatments. Results on microstructure and spatially resolved composition investigations will reveal the micro- and nanostructures of apparently well-known materials after synthesizing and processing them via novel AM methods. |
