Additive manufacturing of intermetallic magnetic materials by electron beam powder bed fusion (B08)

• Subject Area: Synthesis and Properties of Functional Materials ; Materials in Sintering Processes and Generative Manufacturing Processes ; Primary Shaping and Reshaping Technology, Additive Manufacturing
• Term: since 2020
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 405553726

AM will be used to alter the microstructure of Ni-Mn-X with X = In, Sn (or Ga, Al), to increase its mechanical stability to prevent intergranular cracking due the anisotropic volume change during phase transformation and selectively adjust its ferromagnetic transformation range and thermal hysteresis. This will be achieved by modifying the composition of the alloy to adjust the Curie temperature and the martensitic transformation temperature. This project will strongly collaborate with the additive manufacturing projects B11, A10, A11, A06, B13, benefit from characterization by B01, B04, A12, A08 and the machine learning project B12.
