一种铝成分梯度为0 at的功能性梯度铁铝墙体结构。PCT超过50。pct是使用线弧增材制造（WAAM）系统制造的。采用光学显微组织分析、硬度测试、拉伸测试、x射线衍射相表征和电子色散光谱法对制备的合金进行了研究。实验样品的综合分析表明，WAAM体系可用于制备密度充分、成分理想、力学性能合理的铝化铁功能梯度材料。
A functionally gradient iron-aluminum wall structure with aluminum composition gradient from 0 at. pct to over 50 at. pct is fabricated using a wire-arc additive manufacturing (WAAM) system. The as-fabricated alloy is investigated using optical microstructure analysis, hardness testing, tensile testing, X-ray diffraction phase characterization, and electron-dispersive spectrometry. The comprehensive analysis of the experimental samples has shown that the WAAM system can be used for manufacturing iron aluminide functionally graded material with full density, desired composition, and reasonable mechanical properties.
