Abstract : Additional work was performed for the Phase 1 portion of the contract. Testing of finished mill processed 0.020, 0.040, 0.060, and 0.080 in. gage sheet showed the sheets to be quite brittle. Additional total gage removal varying from 0.0050.026 in. from these sheets was beneficial in making more ductile sheets but did not restore the original ductility as indicated by bend test results. These data suggest the existence of metallurgical instability in the alloy arising from mill processing. Mill processing of 0.030 and 0.050 in. gage sheet product, Ti-5Al-5Zr5Sn, Heat XT-70029 is in progress. Tensile test, bend test, and hydrogen content data have been developed for sheets ready for vacuum annealing. Additional total gage removal of 0.006 in. is necessary for the sheets before vacuum annealing. (Author)
