SST Technology Follow-On Program, Phase 1. Mechanical and Metallurgical Characteristics of Titanium Alloy 6Al-4V

Abstract

Mechanical, fracture, and metallurgical tests of Ti-6Al-4V which were halted at the cancellation of the SST program were reinitiated under the DOT Technology Follow-On program. These test data, supplemented by earlier data generated by the SST program, provided a sufficient data base for quantitative analysis of the factors that control Ti-6Al-4V mechanical and fracture properties. Data for continuously rolled sheet, hand-mill sheet, plate, extrusions, bar, and forgings were analyzed by regression analyses to relate alloy composition, microstructure, and crystallographic texture to the properties of strength, fracture toughness, and stress-corrosion resistance. The major variables affecting properties were oxygen and aluminum contents, texture, and ordering of the alpha phase (formation of Ti3Al).
