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 CL20E...
The ferritic Fe-Cr-Ni-Al-Ti alloys strengthened by hierarchical-Ni2TiAl/NiAl or single-Ni2TiAl precipitates have been developed and received great attentions due to their superior creep resistance, as compared to conventional ferritic steels. Although the significant improvement of the creep resistance is achieved in the hierarchical-precipitate-strengthened ferritic alloy, the in-depth underst...
Due to coming emission legislations, the temperature is expected to increase in heavy-duty diesel engines, specifically in the hot-end of the exhaust system affecting components, such as exhaustand turbo manifolds. Since the current material in the turbo manifold, a ductile cast iron named SiMo51, is operating close to its limits there is a need for material development in order to maintain a h...
