Description

A commercial 1045 steel was machined into a hollow cylindrical membrane to investigate the hydrogen permeation and diffusion in the material. The coefficients of hydrogen permeation and diffusion were determined at several temperatures in the range from 250 to 350 °C. The resulting expressions for increasing hydrogen permeability and diffusivity with increasing temperature were 3.958x10-4exp(-84803/RT) and 5.129x10-3exp (-63727/RT), respectively. These results can be used for modelling hydrogen accumulation inside the Hydrogen Effusion Probe (HEP), an on-line instrument for measuring flow-accelerated corrosion,that was manufactured from this material.
