Microstructural characterization of Ti64 fabricated by SLM in vacuum

Abstract

We demonstrated that a Ti-6Al-4V plate, which is clinically used for artificial bone and hard tissue implant in human body because of their light and biocompatibility, were fabricated by selective laser melting (SLM) process in vacuum. In order to investigate the laser melting and solidification dynamics, a process of Ti 64 plate fabrication was captured by a high speed video camera. It was also determined that crystal orientation was evaluated with X-ray diffraction (XRD). It was recorded from the powder peaks of α (1011), α (0002), α (1010), and α (1012) that the crystal orientation is composed mainly of martensitic alpha by XRD analysis. Diffraction peaks corresponding to β (110) were detected in vacuum SLM processed samples.We demonstrated that a Ti-6Al-4V plate, which is clinically used for artificial bone and hard tissue implant in human body because of their light and biocompatibility, were fabricated by selective laser melting (SLM) process in vacuum.
