Abstract

In this study, the effects of TiC heterogeneous nucleation site particles on the formability and microstructure of additive manufactured (AMed) Ti-6Al-4V samples fabricated by selective laser melting are investigated. Laser confocal microscopy and X-ray computer tomography techniques have been applied to AMed samples for visualization of the top surface and pore structures in 3D. The density of AMed Ti-6Al-4V samples was found to be increased by the addition of TiC particles. It could be concluded that the addition of heterogeneous nucleation site particles is one of the key technologies to achieve higher formability, improved microstructure, and enhanced mechanical properties for AMed products.

TiC非均相成核位点颗粒制造的3D打印Ti-6Al-4V样品的顶部表面结构和孔的3D可视化

摘要

在这项研究中，研究了TiC异质形核位点颗粒对通过选择性激光熔融制备的添加剂制造的（AMed）Ti-6Al-4V样品的可成形性和微观结构的影响。激光共聚焦显微镜和X射线计算机断层扫描技术已应用于AMed样品，以可视化3D的顶部表面和孔结构。发现通过添加TiC颗粒可以提高AMed Ti-6Al-4V样品的密度。可以得出结论，添加异质形核位点颗粒是实现AMed产品更高的可成型性，改善的微观结构和增强的机械性能的关键技术之一。
