| Abstract Scope |
An open-die mandrel-forged seamless Ti-6Al-4V ring was subjected to first-article inspection and found to have failing % elongation in one of twelve room temperature tensile specimens. Upon triple-retesting, two of the three retest specimens failed % elongation. The remnants and remaining ring were subjected to a metallurgical investigation to determine the root cause of the repeated failure to meet minimum % elongation requirements. Some insights into the relationship between grain flow and tensile properties in this wrought alloy were presented. |
