Diffusion and trapping of hydrogen in pipeline steels

The charging method enabled to measure an apparent diffusion coefficient,influenced by both lattice diffusion and trapping.The diffusion coefficient obtained by partial charge/discharge and the first stage of complete discharge method was close to the one of pure iron,then it can be reasonably assumed to be the lattice diffusion coefficientsp.info Utility of histogram analysis of apparent diffusion ·INTRODUCTION.Head and neck squamous cell carcinoma (HNSCC) is one of the most frequent malignancies in humans [].Modern imaging modalities can not only correctly stage HNSCC but also provide additional information about tumor structure and behavior [].For instance,diffusion weighted imaging (DWI) by means of apparent diffusion coefficient (ADC) can predict tumor response tosp.info Diffusion tensor imaging for assessment of normally white matter and tracts (P = 0.000).Correlation between average apparent diffusion coefficient of corpus callosum tract and expanded disability status scale score revealed a significant positive correlation in RRMS (P = 0.001).While in secondary progressive MS,a significant negative correlation between fractional anisotropy average of the corpussp.info Previous123456NextCarbon diffusion in carbon-supersaturated ferrite and Feb 15,2014·Carbon diffusion coefficient,D,in carbon-supersaturated lattice was measured.Fe,Fe–Cr and P91 steel (BCC) and Fe–Ni–Cr and AISI 316 (FCC) were studied.• D’s are much lower than data reported for equilibrium carbon concentration..Values of D are close to known data for carbon diffusivity in carbide phase.

Effects of Niobium and Vanadium on Hydrogen-Induced ...

Influence of vanadium and/or niobium additions on delayed fracture behavior in high strength spring steel was studied by hydrogen permeation method and slow strain rate technique (SSRT), and its mechanism was analyzed. The results show that apparent diffusion coefficient of hydrogen in microalloyed spring steels Nb-V-steel and Nb-steel is lower than that in non-microalloyed steel …sp.info Helium-3 MRI diffusion coefficient correlation to The apparent diffusion coefficients were significantly different between the two groups (0.18±0.02 and 0.15±0.01 cm 2 s −1 for elastase and control,respectively).A significant correlation between the apparent diffusion coefficient and corresponding morphometric parameters in mild emphysema was demonstrated for the first time.sp.info ASTM C1556-11a(2016) - TechstreetASTM C1556-11a(2016) Standard Test Method for Determining the Apparent Chloride Diffusion Coefficient of Cementitious Mixtures by Bulk Diffusion.standard by ASTM International,04/01/2016.View all product detailssp.info An Innovative Procedure to Evaluate the Hydrogen Diffusion A large number of metallic alloys are currently under investigation in the field of hydrogen storage and hydrogen separation membranes.For such applications,the knowledge of the hydrogen diffusion coefficient in the given alloy is of great importance even if its direct measurement is not always easy to perform.In this view,the aim of this work is to describe an innovative procedure able to
