... reached the highest temperature in service. A 400x etched micrograph showed a brittle and somewhat porous metallic layer about 0.025 mm (0.001 in.) thick on both surfaces of the sheet. Next to this was an apparently single-phase region nearly 0.05 mm (0.002 in.) in thickness. The examination supported...

... at the point of highest stress, but approximately 200 mm above it. A bell-shaped sheet metal cap was welded onto the shaft at this point. The tubing had fractured about 10 mm under this weld seam. The steel of the shaft tubing contained only 0.033P and 0.004N, and thus was not considered prone to brittle...
