In this study, three kinds of Nickel Aluminide alloys were prepared with different Fe content (0, 0.25, and 1 atomic percentage respectively). We applied indentation to investigate the mechanical performance of the alloys. The deformed areas around the indentation are investigated using the synchrotron x-ray diffraction to map the microstructure distribution of the alloys. After mapping a five by five points, each point aparts 100μm, the distribution of the lattice-strain, diffraction intensity, and peak width of different phases are revealed.
