| Abstract Scope |
In view of property characterization, the present study investigated for understanding an influence of building directions (X and Z) in Wire arc additive manufacturing (WAAM) of two phase (α+β) Ti-6Al-4V alloy.Ti-6Al-4V alloy was deposited layer by layer with an optimized process parameters, where layers comprised of various morphological features viz., basket weave and martensite depending on built (X and Z) directions as witnessed by optical and scanning electron microscopy. Room temperature tensile tests were conducted for X and Z built Ti-6Al-4V samples at the strain rate of 1×10-3 s-1. The obtained mechanical properties of yield strength (YS), ultimate tensile strength (UTS) and elongation for X and Z directions were found to be >860 MPa, >950 MPa and ~1.5%, respectively. The nature of stress-strain curves in various samples could be explained with the help of changes in grain morphology and the volume fractions of the alpha and beta phases. |
