THE DEVELOPMENT OF A SUPERIOR TITANIUM-BASE ALLOY FOR CRYOGENIC APPLICATIONS. VOLUME I.

Abstract

The purpose of this program is to develop a superior Ti-base alloy that exhibits good formability, weldability, and possesses adequate toughness, strength, and ductility for structural applications from ambient to liquid-hydrogen (-423 F) temperatures. This report describes the work performed in Phase I of a three-phase program. A total of thirty-two 4-1/2- to 6-pound ingots were prepared, processed and tested. Experimental compositions were based upon the TiAl, Ti-Al-Sn, and Ti-Al-V systems. The Al contents varied from 5 to 7-1/2%, the Sn from 2-1/2 to 5%, and the V held to 2-1/2%. Other substitutional alloying elements included Zn, Nf, Nb, Ta, and Mo - whose additions varied from 1 to 5%. Experimental procedures describing the melting, reduction of ingot to sheet, and testing are discussed in detail. (Author)
