Abstract:

Studies were continued on the effect of surface contamination on annealed test samples exposed at 1000 F for 150 hr Ti-7Al-12Zr alloy. Total surface removal before and after exposure varied from 0.012 to 0.020 inch. H content had a marked influence on tensile ductility after exposure. Mill processing of the 0.020, 0.040, 0.060, and 0.080-in. ga. sheet Ti-7Al-12Zr alloy was completed. An investigation was conducted on the Ti-5Al-5Zr-5Sn alloy to note the effect on tensile and bend properties of 0.030- and 0.050-in. ga. sheets annealed at 1450 to 1750 F. A limited amount of tensile testing was performed to note the aging effect, if any, on solution treated and aged sheet product there was no apparent aging response for this alpha type alloy. Chemical check analyses made on random as hot rolled sheets of Ti-5Al-5Zr-5Sn showed that the Al, Zr, and Sn contents were uniform. Author
