Cracking susceptibility

This specification covers grades of average wall thickness, or, if specified on the order, minimum wall thickness, of stainless steel tubing for services requiring general corrosion resistance, with particular emphasis on resistance to stress corrosion cracking. These steels are susceptible to embrittlement if used for prolonged periods at elevated temperatures.

This specification covers seamless and straight-seam welded ferritic/austenitic steel pipe intended for general corrosive service, with particular emphasis on resistance to stress corrosion cracking. These steels are susceptible to embrittlement if used for prolonged periods at elevated temperatures.

The authors studied a novel thermal cycling test under tensile loading of the round-notched bar type specimen, using Gleeble test machine. In this kind of testing the mechanism of the DDC is thought to be different from the earlier observations and hypotheses.

These results indicate that Alloys 600 and 182 are susceptible to cracking. The average CGR of the as-welded Alloy 152 was found to be 2.8 109 mm/s. Therefore, Alloy 152 was proven to be highly resistant to cracking. The as-received Alloy 690 showed no crack growth even with an inhomogeneous banded microstructureThese results indicate that Alloys 600 and 182 are susceptible to cracking. The average CGR of the as-welded Alloy 152 was found to be 2.8 109 mm/s. Therefore, Alloy 152 was proven to be highly resistant to cracking.

Increasing irrigation intervals decreased the skin strength and calcium content of the fruit but increased the reducing sugars and ion leakage from skin disks. The data suggest that both pulp and skin characteristics of litchi fruit may determine fruit cracking susceptibility and that increasing the irrigation intervals promotes the incidence of cracking.

Aluminum alloys also display high fatigue crack growth rate, as much as three times faster than in steel specimens when subjected to the same stress intensity (Czyryca et al 2006). Aluminum alloys are anodic to most other materials used in construction and therefore, susceptible to localized galvanic corrosion. They are also sensitive to stress corrosion cracking. Other concerns involve marine fouling since aluminum alloys cannot be coated with conventional Cu-based antifouling coatings. In summary, the U.S.

This concept may also be applied for a structure under constant load to quantify the susceptibility to fracture. Fracture is most likely to occur at locations where high tension stress and/or severe stress con- centration exist. Fatigue cracking due to repeated loading is more likely to occur (will occur sooner) at locations where high Sr and/or low fatigue categories exist.
