High Strength X3NiCoMoTi 18-9-5 Maraging Steel Prepared by Selective Laser Melting from Atomized Powder

Original language description

Maraging steels are generally characterized by excellent mechanical properties, which favour them for various industrial applications. The application field can be further extended by using the selective laser melting (SLM) for additive manufacturing of shape complicated products. However final mechanical properties are strongly related to the microstructure condition. Present work-study the effect of heat treatment on microstructure and mechanical properties of 3D printed samples prepared from powder of high-strength X3NiCoMoTi 18-9-5 maraging steel. It was found that the as-printed material had quite low mechanical properties. After sufficient heat treatment, the hardness of the material increases from 350 to 620 HV0.1 and the tensile yield strength increases from 1000 MPa up to 2000 MPa. In addition, 3% ductility is maintained. This behaviour was primarily affected by strong precipitation during processing.
