The leak was attributed to a crack

The leak was attributed to a crack in the sleeve (Fig. 22), in the radius between the bulb area and the cylindrical portion of
the sleeve. Scanning electron microscope examination of the broken-open crack revealed fatigue cracks initiated at
multiple sites near the outside diameter (OD) of the sleeve (Fig. 23). The crack origins were determined to be extending
from shallow (0.013 mm, or 0.0005 in.) zones exhibiting ductile shear (see area between arrows in Fig. 23). Viewing the
OD surface of the sleeve adjacent to the fracture plane revealed an extensive network of microcracks on the OD in the
radius between the bulb and cylindrical portions (Fig. 24). A cross section through one of the fatigue crack origins
revealed slip bands emanating from the microcracks (Fig. 25)

Mikroskop elektron scanning pemeriksaan Crack patah-terbuka mengungkapkan retak kelelahan yang dimulai dibeberapa situs di dekat diameter luar (OD) lengan (Fig. 23).
