The influence of elastic deformations in high-strength structural materials on the hydrogen transport

The influence of elastic deformations in high-strength structural materials on the hydrogen transport

In this work, the diffusion equation for the gas-solid system is revised to describe the non-uniform distribution of hydrogen in steels. The first attempt to build a theoretical and general model and to describe the diffusion process as driven by a chemical potential gradient is made. A linear elast...
