Mössbauer Spectroscopy for Additive Manufacturing by Selective Laser Melting
نویسندگان
چکیده
Selective laser melting (SLM) is a technology of layer-by-layer additive manufacturing using laser. This allows one to get complex-shaped, three-dimensional (3D) specimens directly from metal powder. In this technology, various powders are used, including different steels. Stainless steel 1.4404 (CL20ES) and maraging 1.2709 (CL50WS) have been investigated. The surface samples manufactured CL20ES CL50WS by SLM (with without combination sandblasting annealing) was studied conversion X-ray Mössbauer spectroscopy (CXMS) electron (CEMS). morphology, elemental composition, structure were examined scanning microscopy (SEM), energy-dispersive (EDS), powder diffraction (XRD). Samples with sandblasted (corundum powder) non-sandblasted surfaces annealed at 540 °C or 550 for 6 h in air. Oxidation processes on both initial observed after post-process annealing CEMS CXMS, as well confirmed XRD. transformation the austenitic ferritic phase sample
