... liquids, and stray electric currents. Most common modes of failure include flaking or pitting (fatigue), cracks or fractures, creep, smearing, wear, softening, indentation, fluting, and corrosion. The modes of failure are illustrated with examples from practice. Roller bearings Rolling-bearing...

... in.). It was fabricated from ten manganese-chromium-nickel-molybdenum-vanadium steel plates 150 mm (5 7 8 in.) thick, which were rolled and welded to form ten cylindrical shell sections and three forgings of similar composition. The forgings formed two end closures and a flange for attaching one of the forged...
