WEB Milling parameters, microstructure evaluation and thermodynamic simulations for oxide dispersed strengthening (ODS) nano-particles for Ni and Fe high-temperature alloy powders for additive manufacturingTuesday (30.06.2020) 11:55 - 11:55 Poster Room Part of:
Nickel-based superalloys and alloys with finely distributed oxide particles (oxide-dispersion-strengthened, ODS) offer significantly better mechanical properties at high temperature, but are currently only conventionally processed or practically not used for various reasons. In the case some Ni-based superalloys with a large fraction of γ‘ phase, crack formation during additive processing is currently one of the main challenges [1, 2]. With regard to Fe-high-temperature ODS alloys, the available conventional manufacturing processes offer only limited geometrical freedom and are also very time- and cost-intensive in application . A continuous additive process chain for ODS alloys would enable the usability of this material group for complex components. As a part of this research, experimental results on milling parameters, microstructure evaluation for ODS alloys and thermodynamic simulations will be presented.
