21. The cause of the embrittlement was tellurium-a fission product generated in the fuel. 22. Chromium, unlike such metals as iron and nickel, does not suffer from hydrogen embrittlement . 23. In materials engineering, the phenomenon of hydrogen embrittlement results from the formation of interstitial hydrides. 24. Metals may diffuse from one base alloy to the other one, causing embrittlement or corrosion. 25. Hydrogen is not used for welding steels and other ferrous materials, because it causes hydrogen embrittlement . 26. This causes embrittlement of boiler parts like rivets, bends and joints, which are under stress. 27. Migration of plasticizers out of their host plastics leads to loss of flexibility, embrittlement , and cracking. 28. The result is slow oxidation and gradual undesirable embrittlement of the polymer on the shelf or in vivo. 29. Corrosion during service in moist environments generates hydrogen, part of which may enter the metal and cause embrittlement . 30. At the same time a program was launched to improve the resistance of Hastelloy-N to the embrittlement .
