Abstract : MAY REPRESENT A COST-EFFECTIVE REPLACEMENT FOR MILLANNEALED Ti-6Al-4V sheet (Ti-64). 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 ASTM Standards E-9 and E-238 cite typical sheet specimens and fixtures for compression and bearing testing, but do not cite any standard specimens or fixtures.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 fixture compatible with the null-balance, servo-measuring system inherent in the test equipment was required. (Author)
