Abstract Scope |
Hybrid steel was produced using maraging steel (MS1) and cold work tool steel (P20). The laser powder bed fusion (LPBF) technique was carried out to deposit MS1 powder on the P20 substrate plate. The as-built MS1-P20 hybrid steels were prepared for microstructural investigations. Scanning electron microscopy (SEM) equipped with energy dispersive spectroscopy (EDS), and electron backscatter diffraction (EBSD) were performed to study the interfacial microstructure. The mechanical properties were evaluated using a microhardness test and a three-point bending test. The investigation showed that MS1 grains followed a non-epitaxial solidification on top of P20 grains, and a cohesive bonding was formed between MS1 and P20 sides. The deposited MS1 obtained higher hardness values than the P20 substrate. In the three-point bending condition, the interface and MS1 side exhibited strong behavior, however, the P20 substrate was remarkably deformed and cracked under extreme tension stresses. |
