Abstract Scope |
Powder bed fusion additive manufacturing (PBF-AM), an efficient technique to fabricate complicated geometries with different metals, is extensively used for shaping Ti6Al4V alloy. Due to having various crucial applications, the high temperature deformation behavior of Ti6Al4V is of interest particularly to aircraft engine manufacturers. Multiple factors influence the high temperature mechanical behavior of this material including the evolution of grain orientation, texture, dislocations and inherent defects. This study analyzes the effect of these microstructural features on mechanical behavior of PBF-AM built Ti6Al4V at various temperatures up to 600°C. Electron back scattered diffraction analysis is conducted on samples before and after the tensile test to determine possible softening mechanisms, microstructural changes and anisotropic behaviors as a function of temperature. Moreover, 3D X-ray CT analysis is conducted to examine the internal defects which varies between 0.05–0.17% depending on the build orientation and their impact on the observed behaviors of the samples. |
