Fatigue crack growth rate, da/dNhttps://www.tec-eurolab.com/eu-en/fatigue-crack-growth-rate-dadn.aspxGlossary of terms > Fatigue crack growth rate, da/dN Fatigue crack growth rate, da/dN The rate of crack extension caused by constant-amplitude fatigue loading, expressed in terms of crack extension per cycle of load application.
Penetrabilityhttps://www.tec-eurolab.com/eu-en/penetrability.aspxGlossary of terms > Penetrability Penetrability The property of a penetrant that causes it to find its way into very fine openings, such as cracks.
Stress Corrosion Cracking (SCC) type corrosion of flexible inox pipe, Insightshttps://www.tec-eurolab.com/eu-en/stress-corrosion-cracking-scc-type-corrosion-of-flexible-inox-pipe.aspxInsights > Stress Corrosion Cracking (SCC) type corrosion of flexible inox pipe Stress Corrosion Cracking (SCC) type corrosion of flexible inox pipe The objective was to define the corrosion causes Starting from visual analysis and classification it proceded by classifying the phenomenon in terms of chemistry and metallurgy of the metal [...]
Corrosionhttps://www.tec-eurolab.com/eu-en/corrosion-v1.aspxErosion is a strictly mechanical form of corrosion that is caused by friction. There is another type of erosion, which is caused by high speed water flow.
Microscopic characteristics of fatigue failurehttps://www.tec-eurolab.com/eu-en/microscopic-characteristics-of-fatigue-failure.aspxHowever, as the crack gradually propagates, the spacing between striations increases and the crack grows at an increasingly rapid rate because the crack greatly weakens the section. ... Artifacts caused by rubbing or other postfracture damage may produce parallel ridges that resemble striations.
Causes of brittle fracturehttps://www.tec-eurolab.com/eu-en/causes-of-brittle-fracture.aspxGlossary of terms > Causes of brittle fracture Causes of brittle fracture Brittle fractures that occur in service are invariably initiated by defects that are initially present in the manufactured product or fabricated structure or by defects that develop during service. ... Notches, which are discontinuities caused by abrupt changes in the [...]
Striations or beachmarks?https://www.tec-eurolab.com/eu-en/striations-or-beachmarks.aspxThe other difference between striations and beachmarks, as previously mentioned, is the factors that cause them. ... Consequently, the fatigue action causes the necessary tensile stress at this location when the load is released, not when it is applied.
Compression fatiguehttps://www.tec-eurolab.com/eu-en/compression-fatigue.aspxConsequently, the fatigue action causes the necessary tensile stress at this location when the load is released, not when it is applied. With continued operation, radial fatigue cracks will form at the upper corner.
Adhesive wearhttps://www.tec-eurolab.com/eu-en/adhesive-wear-V1.aspxAdhesive wear is quite similar to grinding burn in that both can cause tempering of the subsurface regions and actual rehardening of steel microstructures, resulting in white, untempered martensite, which is extremely susceptible to cracking because of its brittleness. These cracks can lead to either brittle fracture or fatigue fracture, [...]
Crevice corrosionhttps://www.tec-eurolab.com/eu-en/crevice-corrosion.aspxDifferential aeration beneath solid deposits or at cracks in mill scale is a frequent cause of crevice corrosion in boilers and heat exchangers.
