摘要
采用统计实验设计(DOEs)方法确定了近β合金Ti-55511的定向能沉积(DED)参数。通过两个连续的 DOE,确定了导致完全致密自由形态沉积的参数。在初始 DOE 中,使用多种激光功率、横移速率和粉末进给速率设置打印单个激光轨迹,以确定有前景的构建参数。利用捕获效率和有效沉积率对单轨沉积物进行表征和排序。然后,在第二次 DOE 中使用最佳参数打印具有各种 X-Y 和 Z 重叠(不同的舱口间距 HS 和层厚度 ZS)的实心立方体。根据立方体的密度和微观结构选择合适的沉积参数,并用于制造较大的拉伸样品进行机械测试。发现多个参数集可提供具有可接受机械性能的致密 Ti-55511 沉积物,并且参数模型显示出统计学意义。
Investigation of Deposition Parameters for Near-Beta Alloy Ti-55511 Fabricated by Directed Energy Deposition
The directed energy deposition (DED) parameters were determined for near-β alloy Ti-55511 by employing statistical design of experiments (DOEs) methods. Parameters resulting in fully dense freeform deposits were identified using two sequential DOEs. Single laser tracks were printed with several laser power, traverse rate, and powder feed rate settings in an initial DOE to identify promising build parameters. The capture efficiency and effective deposition rate were used to characterize and rank the single track deposits. The best parameters were then used to print a solid cube with various X–Y and Z overlaps (different hatch spacing, HS, and layer thickness, ZS) in a second DOE. Suitable deposition parameters were selected based on the cube density and microstructure and were used to fabricate larger tensile samples for mechanical testing. Multiple parameter sets were found to provide dense Ti-55511 deposits with acceptable mechanical properties and the parametric models showed statistical significance.
