... for examination. Transverse sections through this and the mating portion already received, followed by magnetic crack detection, revealed the presence of defective zones. Subsequent ultrasonic examination of other sections of the steam main indicated suspect areas in a number of lengths of pipe. These defects...

... Abstract The stub-shaft assembly which was part of the agitator shaft in a polyvinyl chloride reactor, fractured in service after a nut that retained a loose sleeve around the smaller-diam section of the shaft had been tightened several times to reduce leakage. The shaft was made of ASTM A105...

... of the authors [1] had established that aluminum alloys of the type used in aircraft exhibited a “reversing shear” fracture surface ( Fig. 1 ) when exposed close to an explosion center. When we examined fracture surfaces of sections from the crash, we noted the normal shear type of separation on most of them...
