Hydrogen Interactions with Defects in Materials

This manuscript summarizes basic properties of hydrogen in materials, mainly metals, and resulting consequences for the materials properties, including recent developments. It emphasises to introduce into the field of hydrogen in metals in a focused manner. It addresses hydrogen solution in materials, hydride formation, hydrogen diffusion and permeation and the interaction of hydrogen with defects. The influence of hydrogen on the defect energies and consequences for the metal behaviour are addressed. Further, the influence of constraint conditions on the system properties is shortly discussed.
