The principal types of elevated-temperature failures are stress rupture, creep, low- or high-cycle fatigue, thermal fatigue, and coating degradation in gas turbines. For high-temperature tubing and piping components, embrittlement phenomena can occur...

... specimens. In a similar study ( Ref 25 ), the influence of liquid zinc at 425 to 500 °C (795 to 930 °F) on various steels was tested using bend, tensile, and creep-rupture specimens. Grain-boundary penetration of the zinc into the steels was observed. Another study investigated intercrystalline failures...

A mechanism of intergranular creep rupture at elevated temperature was identified as a result of a series of stress-rupture and tensile tests. It was revealed by the crack shape that cracking initiated on the pipe exterior, then propagated inward...
