| Popis: | Tension, notch-tension, bend, and sustained-load tests have been employed in the examination of the hydrogen-embrittlement of high-strength 4340 steel. Hydrogen was introduced into the specimens under conditions corresponding to cleaning and plating conditions. Hydrogen-embrittlement in the static tests was found to depend on the strain rates used, in agreement with previous work. However, the rate of recovery from hydrogen embrittlement was found to differ for the cathodically cleaned and plated specimens. Failure in the sustained-load tests was shown to result from the development of a surface crack which, through growth, reduced the load-bearing cross section, with a consequent increase in the nominal stress on the section to a value equal to the fracture stress. |
