    on the surface of high resistance materials resulting in low. ductility and increased internal stress. • Hydrogen induced cracking and hydrogen stress cracking: blister formation that may affect the integrity of materials. especially when stressed. Combined, this means that in any facility that has
  • Medical Device Link . Evaluating Environmental Stress Cracking of Medical Plastics
    . Solvent-induced crystallization may have a pronounced effect on stress-cracking behavior, as will be discussed later. Although both amorphous and crystalline plastics are susceptible to environmental stress cracking, it is generally recognized that amorphous plastics tend to be more at risk.3 5

    and transported in steel pipelines; however, at the gas. pressures needed for commercial distribution of hydrogen in support of the hydrogen economy, steels. become more susceptible to hydrogen-induced crack growth and embrittlement. Changing the gas. composition and/or the steel composition are two
  • Fastener Failure Analysis: Fracture Failure of Countersunk Flat Head Screws Case
    embrittlement, also called hydrogen induced cracking. Discussion. All evidence and test results indicate that the screws identified in the A and B bags failed as a consequence of hydrogen embrittlement. Hydrogen embrittlement was confirmed by SEM examination that was characterized by intergranular fracture
  • Low Speed Carbon Deposition Process for Hermetic Optical Fibers (.pdf)
    For optical fibers used in adverse environments, a carbon coating is frequently deposited on the fiber surface to prevent water and hydrogen ingression that lead respectively to strength degradation through fatigue and hydrogen-induced attenuation. The deposition of a hermetic carbon coating onto
  • Fractography of Metals and Plastics (.pdf)
    common to both metals and plastics include ductile overload, brittle fracture, impact, and fatigue. Analogies can also be drawn between stress-corrosion cracking (SCC) of metals and stress cracking of polymers. Other metal/plastic failure analogies include corrosion/ chemical aging, dealloying/ scission

The natural abilities of the water to decompose the hydrocarbons become overwhelmed and the. resulting affect on the environment includes, but is not limited to: -oils
