Abstract
Ti6Al4V (Ti64) plate was fabricated from powders in vacuum at 10−2 Pa by selective laser melting (SLM) method with single mode fiber laser. Ti64 has a crystal orientation of alpha α + β type. In order to investigate the crystal orientation, a X-ray diffraction in continuous scanning mode and an energy dispersive X-ray spectroscopy were conducted. From the results, it can be found that at the powder, the peak of α (1011), α (0002), α (1010) and α(1012) crystal orientations is detected to be composed mainly of martensitic alpha. Diffraction peaks corresponding to β(110) were detected in vacuum SLM processed samples.Ti6Al4V (Ti64) plate was fabricated from powders in vacuum at 10−2 Pa by selective laser melting (SLM) method with single mode fiber laser.
