What is a Brittle Failure? - Definition from Corrosionpedia

Non-brittle steel becomes brittle at low temperatures based on their processing and composition.A metal that is naturally malleable is made stronger by obstructing the mechanics of plastic deformation.But,if it is pushed to the extreme,the material becomes brittle and fracturing is a likely outcome.Various Types of Corrosion in Metals MetallurgyHydrogen-Embrittlement 8.Corrosion-Fatigue 9.Erosion-Corrosion and Few Others.Types # 1.Uniform Corrosion If corrosion is such that the whole surface of the metal is corroded to the same degree,and the metal becomes thinner uniformly to eventually fail,it is called uniform corrosion.The mechanism could be chemical,or electro-chemical The hydrogen embrittlement of metals - ScienceDirectThe conclusions from each of these individual reviews are then combined in the proposal of a general theory of the hydrogen embrittlement of metals which not only incorporates the essential features of each case of hydrogen embrittlement,but also suggests an explanation for the absence of similar effects in other metals.

Strain-Age Hardening and Brittleness in Chromium -

CURRENT theories of the cause of brittleness in `pure' chromium ascribe the phenomenon to Cottrell locking 1 ,invoking the Mott-Stroh 2,3 theory of crack formation as the operative mechanism of brittle fracture,and nitrogen as the associated interstitial solute atom.There are several features of the tensile behaviour of annealed chromium (containing approximately 0.002 per cent nitrogen and Some results are removed in response to a notice of local law requirement.For more information,please see here.Previous123456Next(PDF) Review of Hydrogen Embrittlement in MetalsA preview of this full-text is provided by Springer Nature.Download full-text PDF Table 3 Similarities and dierences of dierent hydrogen Review of Hydrogen Embrittlement in Metals Some results are removed in response to a notice of local law requirement.For more information,please see here.12345Next(PDF) Mechanism of Embrittlement of Metals by Surface mechanism of embrittlement of metals by surface-active elements 205 Ab initio calculations of the effect of surfactants on the electron structure have been performed using iodine in the - iron.

Atomistic calculations using pair potential interactions verified these findings.It was initially thought that the helium embrittlement in metals was due to the trapping and subsequent bubble formation at radiation-induced defects.It has been shown,however,that helium may be trapped in metals even in the absence of radiation damage.Prevention of Hydrogen Embrittlement in SteelsPrevention of Hydrogen Embrittlement in Steels H.K.D.H.Bhadeshiaa aMaterials Science and Metallurgy,University of Cambridge,U.K Abstract The essential facts about the nature of the hydrogen embrittlement of steels have now been known for 140 years.It is diusible hydrogen that is harmful to the toughness of iron.
