Abstract:

The alloy maintained about 85 of its room temperature yield strength and 82 of its ultimate strength when tested at 260 F after a 100-hour exposure to 260 F. The percent elongation at room temperature was 10.3 for the longitudinal specimens, 8.2 for the long transverse, and 2.5 for the short transverse specimens. The ultimate shear strength to ultimate tensile strength ratio was about 0.6. The flatwise bearing test specimens exhibited a higher ultimate strength than the edgewise specimens. The difference was 12 for the eD ratio of 1.5 and 14 for the eD ratio of 2.0. The flatwise bearing test specimens with eD ratio of 1.5 had 8 higher average bearing yield strength values than the corresponding edgewise specimens. The bearing yield strengths for an eD ratio of 2.0 were approximately equal for edgewise and flatwise specimens. Typical failures of bearing specimens are given. There were some differences in the properties of the three test blocks. Author
