Hydrogen, being a small atom, fits in between the larger metal atoms so can dissolve within the metallic structure. This generally causes the metal to become brittle and easily cracked. This example is from a steel hydrocarbon pipeline where hydrogen, generated by corrosion, has dissolved on the external metal surface and transported to form high pressure gas bubbles within the steel.
