Notes:
Notched tensile tests were performed to evaluate the presence of notch on the tensilestrength of Ti-6Al-6V-2Sn laser welds, which were post-weld aged at different temperatures.Ti-6Al-6V-2Sn laser welds showed notch brittleness except for the welds aged at/above 704 oC. Fineacicular α uniformly distributed in β matrix in the fusion zone accounted for the high hardness (Hv440) as compared with mill-annealed base metal. Overaging at/above 704 oC resulted in coarseningthe microstructures and decreased notch brittleness. The fracture features of the weld were stronglyaffected by the orientation of the solidified structures with respect to the crack growth direction
