In response to that gradient, the rate-controlling transport step depends on molten binder flow in the pores, binder evaporation, or vapor permeation through the pores. The latter is not rate controlling for thin...

... and catastrophic brittle failure. Atomic hydrogen permeates the steel and reduces iron carbide (Fe 3 C) to form methane (CH 4 ). The methane does not diffuse from the metal, and its pressure may exceed the cohesive strength of the metal and cause fissuring between grains. Figure 12 shows the effects of HTHA...

...), nitridation by molecular nitrogen can become a serious material issue. Under oxidation/nitridation conditions, nitrogen molecules permeate through cracks and pores and reach the metal underneath the oxide scales when the oxide scale is no longer protective. Nitridation then proceeds by dissociation...
