| Abstract Scope |
This work explores the effect of processing parameters on texture development in Ti-6Al-4V wall components fabricated by wire-feed Directed Energy Deposition process, one of the additive manufacturing techniques. Microstructure and texture were characterized using scanning electron microscopy (SEM) and electron backscatter diffraction (EBSD). An open source software package, MTEX, was used to perform grain reconstruction, orientation analysis, variant selection analysis, and generate IPF maps. A viscoplastic self-consistent (VPSC) model was used to simulate the deformation response under uniaxial tension applied along vertical, horizontal, and diagonal directions with respect to the build direction of the single wall component. A strong variation in texture was observed along the build direction in laser hot wire deposited single walls. VPSC simulation confirmed the tension-compression asymmetry and the anisotropic response of Ti-6Al-4V single walls. The horizontal stress was found to be higher as compared to vertical and diagonal stresses. |
