| beschreibung | 12CrNi2 high strength steel thin wall with few defects was fabricated by laser additive manufacturing technology. The microstructure of as-built sample was studied using optical microscopy (OM), scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). Additionally, the mechanical property was also investigated by microhardness tests. It was found that the microstructure of the as-built sample mainly consists of columnar dendrites aligned in building direction because of the fast directional cooling during LAM. Cellular grains, and equiaxial dendrites are also observed in different regions of the as-built sample due to heat accumulation effect. Furthermore, many types of microstructure, such as tempered martensite, M-A constituent, retained austenite, lower and upper bainitic ferrite, are appeared in the as-built sample resulting from complex heat history and wide temperature range during LAM process. The maximum and minimum microhardness (499 HV 0.2 ... |
