Data are presented for evaluations conducted on the 5Al-5Sn-5Zr and 7Al-12Zr alloys to determine the precautions necessary to prevent stress corrosion cracking problems during forming. Nomal precautions during manufacturing to prevent contamination of the 5Al-2 12Sn titanium alloy details are adequate for the super alpha titanium alloys. A range of 1300 F for two and one half hours to 1500 F for one half hor produces 88 to 100 stress relief of both alloys.
