该数据是对粉末样品、标样和LPBF制备的FeCrAl合金方块样品的X射线衍射结果，其中均出现了α-Fe和Fe2AlCr相的衍射峰，粉末样品的{200}晶面衍射强度较低但{211}晶面的衍射强度高，衍射峰更加尖锐；方块样品和标样的衍射峰形状类似，晶体结构一致。

The data were the X-ray diffraction results of powder sample, standard sample and FeCrAl alloy sample prepared by LPBF. The diffraction peaks of α-Fe and Fe2AlCr appeared in all of them. The diffraction intensity of {200} crystal plane of powder sample was lower, but the diffraction intensity of {211} crystal plane was higher, and the diffraction peak was sharper. The diffraction peaks of the square sample and the standard sample were similar in shape and the crystal structure was consistent.
