SST Technology Follow-On Program, Phase I. Titanium Alloy 6Al-4V Extrusions

Abstract

Various investigations were conducted to characterize and develop Ti- 6Al-4V extrusions. In addition to Ti-6Al-4V, the initial developmental studies also included Ti-6Al-6V-2Sn extrusions. Properties evaluated included strength, fracture toughness, stress corrosion resistance (K sub ISCC), fatigue and metallurgical characteristics. The extrusion properties were highly variable. Strength and fracture property variations were associated with significant variations in chemical composition, microstructure and crystallographic texture. High fracture characteristics were related to relatively low oxygen contents, fully transformed beta microstructure and near non-directional textures.
