Determination of basic strength properties of Ti--8Mo--8V--2Fe--3Al sheet

OSTI ID:4330508
Examination of the various room-temperature mechanical properties of the beta-alloy Ti-8Mo-8V--2Fe- 3Al sheet (Ti8823) in the stabilized heat-treated condition indicates that this material may represent a cost-effective replacement for millannealed Ti-8Al-4V sheet (Ti-84). With approximately equal elastic moduli, the strength properties are higher for the stabilized Ti-8823 than for the mill-annealed Ti-64. The examination also indicates that for improved strength properties of solutionized, cold-rolled, and aged Ti-8823, either a greater amount of cold working or longer aging time is probably needed. ASTM Standards E-9 and E-238 cite typical sheet specimens and fixtures for compression and bearing testing, but do not cite any standard specimens or fixtures. Therefore, in this study the development of a compression and hearing test finture compatible with the null-balance, servo-measuring system inherent in the test equipment was required. (auth)
