DEVELOPMENT OF A HEAT TREATABLE TITANIUM SHEET ALLOT

摘要

The objective of this research program was to develop heat treatable titanium sheet alloys capable of providing 160,000 psi yield strength, 0.2％ offset, at room temperature. The material should be easily rolled to light gages, of the order of 0.020 in., possess excellent formability in the solution-treated condition, and be stable under stress, as heat treated, for at least 500 hours at 600° and 800°F. Good weldability was secondary in desirability to the foregoing requirements.nThe program was divided into two parts, designated as Phase I and Phase II. Phase I had as its purpose the screening of fifteen alloys in order to select the four most promising for more intensive investigation in Phase II.
