The effect of stress on the growth of gas bubbles during irradiation

Tensile and stress corrosion cracking behavior of ferritic–martensitic steels in supercritical water

“…Chromium increased strength by the solid solution strengthening. The observed trend is consistent with the work of Bullough et al [14] where hardening increases with increasing bulk Cr concentration. In addition, chromium and carbon are both important in precipitation strengthening.…”

Mechanical properties of high-nickel alloys EP-753 and РЕ-16 after neutron irradiation to 54 dpa at 400–650 °С

“…Ignoring hydrogen's possible role for the moment, the possibility has been raised that helium bubbles forming and growing on grain boundaries under applied stress might account for all or some fraction of the observed embrittlement [27]. Since nickel is the major source of helium and hydrogen in fast reactor neutron spectra [5,6,22], it is expected that high-nickel alloys might be particularly prone to such a process.…”

Creep and cavity growth under multiaxial stresses

“…This gives rise to a displacement of the upper surface of plcos 4, so that the creep rate fied if free surfaces, instead of grain boundaries, provide the major source of vacancies. Cavity growth then depends simply on the hydrostatic component of the applied stress (Bullough, Harries and Haynes 1980). This case, however, will not be considered further in the present paper which principally relates to polycrystalline material where grain-boundary vacancy sources are usually much more prominent than those of free surface (Harris 1976).…”
