Key Objectives: 

• 1. Phase Precipitation Analysis: Investigating phase kinetics during DED to better understand the relationships with process parameters, temperature distribution and microstructure. 
• 2. Strain Build-up Monitoring: Utilizing neutron diffraction to characterize dynamic stress and strain evolution during the DED process. 
• 3. Traditional Laboratory Characterization: Correlating microstructural details with in-situ and ex-situ measurements to enhance understanding of material properties.

The PhaNi-Neutron project, conducted by the Fraunhofer Institute for Material and Beam Technology IWS,
focused on the phase and strain monitoring during the laser based direct energy deposition (DED-LB/M) of
Ni-superalloys using in-situ neutron and synchrotron diffraction techniques. The project aimed to enhance
the understanding of the solidification processes and phase evolution in additive manufacturing, specifically for the nickel superalloys IN718 and IN625.
