SST Technology Follow-On Program, Phase 1. Compatibility of SST Materials with Titanium Alloys. Volume 2. Manufacturing-Aid Materials

Abstract

This document presents data on the compatibility of titanium alloys Ti-8Al-1Mo-1V and Ti-6Al-4V with manufacturing aid materials, which might have contacted titanium during fabrication of the U.S.A. supersonic transport. Testing procedures are described and results are tabulated. Test methods included use of a simple U-bend specimen, use of Heimerl-Braski self-stressed specimens, application of the Allison bend test for detection of surface embrittlement, emittance measurements, and analyses for the hydrogen and oxygen content of exposed titanium, and for the chlorine content of manufacturing aid materials. For each material-specimen-test parameter combination a rating of compatible or incompatible is assigned. Sections are included on the nature of the stress-corrosion cracking produced by the action of hot salt and of methanol on the alloys. Photomicrographs of fracture surfaces are included.
