Abstract Scope |
Due to potential disruptions in supply, several minerals have been categorized as critical in short-term (2020 – 2025) and in medium-term (2025 – 2035). Among these critical minerals with a risk of supply, minerals relevant to clean energy is also defined. It is therefore important to develop novel materials used in the energy sector that do not heavily rely on critical minerals. Cobalt (Co) and nickel (Ni) are two such examples found in nuclear reactor structural materials such as Inconel 617, stainless steel 316H, and alloy 709. Here, an effort that was carried out in fabricating chemically modified IN617 with low levels of critical minerals to have equal or better chemical and physical properties to that of those originally. Microstructural examination, phase identification, chemical composition and mechanical properties from as cast and additive manufactured material will be presented and validated against computational predictions. |
