摘要

使用激光粉末床熔融(L-PBF)AM 技术制造零件的参数开发和工艺鉴定的完整工作流程需要孔隙率、孔形态、变形和静态机械性能数据。结合使用两种非破坏性技术:计算机断层扫描和压痕测试这两种非破坏性技术的结合,描述了打印参数对 Ti-6Al-4V L-PBF 中缺陷类型和零件密度的影响。此外,还将使用组合方法得出的结果与传统测试方法进行了比较。

Influence of printing parameters on part density in L-BPF of Ti-6Al-4V and correlation with static mechanical properties measured using indentation testing
A complete workflow of parameter development and process qualification of a part manufactured using laser powder bed fusion (L-PBF) AM technique requires data of porosity, pore morphology, distortion and static mechanical properties. Using a combination of two non-destructive techniques: Computed tomography and indentation testing, the influence of printing parameters on defect types and part density in L-PBF of Ti-6Al-4V is described. In addition, the results using the combined method are compared to conventional testing methods.
