Theory for Hydrogen Desorption in Ferritic Steel
After a concise review of the analytical models available for the interpretation of thermal desorption rates for hydrogen effusion from steel, a numerical method that incorporates the essence of local equilibrium and detrapping kinetics has been implemented to account for the real complexity of practical experiments. For example, the model permits the treatment of multiple kinds of traps, uses ...
متن کاملCreep and Fatigue Interaction Behavior in Sanicro 25 Heat Resistant Austenitic Stainless Steel
Sanicro 25 is a newly developed advanced high strength heat resistant austenitic stainless steel. The material shows good resistance to steam oxidation and flue gas corrosion, and has higher creep rupture strength than other austenitic stainless steels available today. It is thus an excellent candidate for superheaters and reheaters for advanced ultra-super critical power plants with efficiency...
متن کاملThermal Desorption Analysis of Hydrogen in Non-hydrogen-Charged Rolling Contact Fatigue- Tested 100Cr6 steel
Hydrogen diffusion during rolling contact fatigue (RCF) is considered a potential root cause or accelerator of white etching cracks (WECs) in wind turbine gearbox bearing steels. Hydrogen entry into the bearing steel during operation is thought to occur either through the contact surface itself, or through cracks that breach the contact surface, in both cases by the decomposition of lubricant t...

متن کاملPrecipitation sequence in niobium-alloyed ferritic stainless steel
Niobium is an important alloying element in the design of heat-resistant ferritic stainless steels for automotive exhaust systems. When in solid solution, it improves both the high temperature strength and the resistance to thermal fatigue. However, it also forms several kinds of precipitates during service. These reactions have been modelled, taking into account the multicomponent nature of th...
