  2. Fatigue (material) - Wikipedia

    en.wikipedia.org/wiki/Fatigue_(material)

    Fatigue has traditionally been associated with the failure of metal components which led to the term metal fatigue. In the nineteenth century, the sudden failing of metal railway axles was thought to be caused by the metal crystallising because of the brittle appearance of the fracture surface, but this has since been disproved.

  3. Corrosion fatigue - Wikipedia

    en.wikipedia.org/wiki/Corrosion_fatigue

    In true corrosion fatigue, the fatigue-crack-growth rate is enhanced by corrosion; this effect is seen in all three regions of the fatigue-crack growth-rate diagram. The diagram on the left is a schematic of crack-growth rate under true corrosion fatigue; the curve shifts to a lower stress-intensity-factor range in the corrosive environment.

    mild steel cracks in the presence of alkali (e.g. boiler cracking and caustic stress corrosion cracking) and nitrates; copper alloys crack in ammoniacal solutions (season cracking); high-tensile steels have been known to crack in an unexpectedly brittle manner in a whole variety of aqueous environments, especially when chlorides are present.

    For example, if the replacement cost — not the amount that you paid for it originally, but the amount it would cost to replace it today — for your roof is $20,000, but the roof loses 5 percent ...

  7. Metallurgical failure analysis - Wikipedia

    en.wikipedia.org/wiki/Metallurgical_failure_analysis

    Metallurgical failure analysis is the process to determine the mechanism that has caused a metal component to fail.It can identify the cause of failure, providing insight into the root cause and potential solutions to prevent similar failures in the future, as well as culpability, which is important in legal cases.
