Superior fatigue behaviour, as measured by the fatigue crack growth rate. [Pg.841]

Now the measured value of KIc or GIc is dependent upon the sharpness of the crack employed and an essential requirement of fracture mechanics testing is that a "naturally sharp crack is used for the experimental determination of K,c or G C. If a relatively blunt crack is used, an optimistically high value of KIc or G,c may be recorded. Suitable techniques include slow, controlled pressure applied to a razor blade, possibly having pre-cooled the specimen in liquid nitrogen and fatigue crack growth. [Pg.49]

A list of alloys for which fatigue crack growth rates were measured is shown in Table I. Included are the material forms, chemical analyses heat treatments, and specimen orientations, according to the ASTM Method E 399-74 notation [% One of the Ti-5Al-2.5Sn alloys contained too much hydrogen (173 ppm) to qualify as an extra-low-interstitial (ELI) grade this material is referred to in the text as a low-interstitial alloy. The compact specimen geometry was chosen because it is standardized and much experience has been accumulated with it. Constant-load... [Pg.82]
