2. Dye penetrant inspection - Wikipedia

   en.wikipedia.org/wiki/Dye_penetrant_inspection

   The oil and whiting method used in the railroad industry in the early 1900s was the first recognized use of the principles of penetrants to detect cracks. The oil and whiting method used an oil solvent for cleaning followed by the application of a whiting or chalk coating, which absorbed oil from the cracks revealing their locations.

3. Stress corrosion cracking - Wikipedia

   en.wikipedia.org/wiki/Stress_corrosion_cracking

   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.

4. Crazing - Wikipedia

   en.wikipedia.org/wiki/Crazing

   Unlike cracks, crazes can transmit load between their two faces through these fibrils. Crazes typically initiate when applied tensile stress causes microvoids to nucleate at points of high stress concentration within the polymer, such as those created by scratches, flaws, cracks, dust particles, and molecular heterogeneities.

6. Crack arrestor - Wikipedia

   en.wikipedia.org/wiki/Crack_arrestor

   A crack arrestor (otherwise known as a rip-stop doubler) is a structural engineering device. Being typically shaped into ring or strip, and composed of a strong material, it serves to contain stress corrosion cracking or fatigue cracking, helping to prevent the catastrophic failure of a device.

7. Cured-in-place pipe - Wikipedia

   en.wikipedia.org/wiki/Cured-in-place_pipe

   The process of CIPP involves inserting and running a felt lining into a preexisting pipe that is the subject of repair. Resin within the liner is then exposed to a curing element to harden it and make it attach to the inner walls of the pipe. Once fully cured, the lining now acts as a new pipeline.
