Abstract Scope |
Ti6Al4V alloy, originally developed for aerospace applications, has found wide acceptance in various industries due to its high strength and low density. EB-PBF additive manufacturing is an efficient technique to fabricate complicated geometries with this hard metal. High temperature deformation behavior of Ti6Al4V is very crucial specially to the aircraft engine manufacturers. Therefore, this study focuses on the anisotropic mechanical behaviors at elevated temperatures along with potential reasons for these behaviors. Ti6Al4V alloy is observed to experience flow softening during hot deformation around 600°C temperature. Electron back scattered diffraction (EBSD) analysis is conducted using samples before and after the tensile test to determine possible softening mechanisms and microstructural changes. Microstructural features such as crystallographic texture and grain boundary misorientation angles are investigated via different EBSD maps. Moreover, a 3D X-ray CT analysis is conducted on the samples to investigate the internal defects and their impact on the inherent anisotropic behavior. |
