Neutron Science 085 fundamental tensors and proposing the role of stacking faults for HEA using neutron diffraction measurements in situ. The highly cited “ in-situ neutron diffraction studies on high-temperature deformation behavior in a CoCrFeMnNi high-entropy alloy” 6 is the first paper using neutron diffrac- tion to demonstrate the creep behavior of the HEA. More- over, Huang’s team quantifies the vacancy concentration using neutron diffraction; Huang’s group is the earliest few to point out the elemental effects on HEA vacancy and heterogeneous lattice distortion subjected to quasi- equilibrium heating. 7 For improved fatigue life, neutron diffraction measurements explain why HEA are promising for longer lifetime. 8 In summary, this report shows systematic research using multi-scale neutron measurements for research on AM and High Entropy Alloys. The underlying mechanisms are revealed for better design and fabrication of the advanced metallurgy.
