In this study, we examined the effects of an aluminization process on the microstructure and texture of Haynes 282 nickel samples fabricated using the direct metal laser sintering technique. The aluminization process involved the use of chemical vapor deposition with AlCl vapors in a hydrogen atmosphere at a temperature of 1040 °C for 8 h. Following the 3D printing and aluminization steps, we analyzed the microstructure of the Haynes 282 nickel alloy samples using light microscopy and scanning electron microscopy. Additionally, we investigated the texture using X-ray diffractometry. A texture analysis revealed that after the process of direct laser sintering of metals, the texture of the Haynes 282 nickel alloy samples developed a texture typical of cast materials. Then, in the aluminization process, the texture was transformed-from foundry-type components to a texture characteristic of recrystallization.
在本研究中，我们研究了渗铝工艺对采用直接金属激光烧结技术制造的Haynes 282镍样品的微观结构和织构的影响。渗铝工艺包括在1040°C的氢气气氛中，使用AlCl蒸汽通过化学气相沉积法处理8小时。在完成3D打印和渗铝步骤后，我们使用光学显微镜和扫描电子显微镜分析了Haynes 282镍合金样品的微观结构。此外，我们使用X射线衍射仪研究了织构。织构分析表明，在金属直接激光烧结过程之后，Haynes 282镍合金样品的织构发展出了铸造材料典型的织构。然后，在渗铝过程中，织构从铸造类型的组分转变为再结晶特征的织构。
