EVALUATION OF THE PRODUCIBILITY OF TWO NEW TITANIUM BASE SHEET ALLOYS, TI-7A1-12ZR AND TI-5A1-5ZR-5SN

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)
