| dc.description.abstract | A study of liquid mercury and hydrogen embrittlement was conducted on a 4142 steel. A computer program was developed to generate engineering stress-strain graphs in. order to further enhance the fractographs of samples from air, mercury or hydrogen environments. This program was developed to use load and displacement values of the MTS machine in the stroke control mode in order to control strain rate accurately. Various axisymmetric geometries may be used and samples of reasonably close geometries may be compared for their respective stress-strain character-. istics. The study revealed that hydrogen and mercury samples do have the intergranular characteristic fractures of adsorption induced reduction in cohesion, but the graphs of comparable mercury and hydrogen samples show a difference. Hydrogen samples break before the nominal yield strength while mercury samples break after yield. Study of this steel reveals trends in strain rate and microstructure worthy of further investigation and is recommended with the aid of the MTS stress-strain program. | |
