The initial starting point of the project consideration was the demand of industrial enterprises for materials that combine an outstanding corrosion resistance in aggressive high-temperature environments with excellent mechanical properties at extremely high temperatures of up to 1350¡ãC. Candidate materials, e. g. the ODS Fe-based alloy PM2000, or the ODS Cu-based alloy GlidCop are extremely difficult to machine, and their market availability will disappear. The rapid development of advanced AM processes will require a paradigm change, i. e. tailoring new materials towards the particular AM process chain and the technical application.

In this context, ODS alloys were identified as promising candidate materials to produce highly individualized burner heads and high-temperature heat exchangers, that are utilized in aggressive high-temperature environments, e. g., rectisol plants or steam reformer methanol reactors. Gradual adaptation of the thermal conductivity and thermal expansion, the ability to form protective oxide and healing layers tailored for the respective aggressive environment, and the ODS mechanism in combination with the high degree of freedom in L-PBF will form the corner stone of multifunctional material systems that allows for a tailor-made design of technical devices exposed to extreme operation conditions.
