The effect of hydrogen existence on the formation of lattice defects by the strain for pure iron and cold-drawn pearlite steel. The thermal desorption analysis (TDA) of hydrogen and the positron annihilation lifetime measurements gave that the interaction between hydrogen and strain could enhance the formation of the lattice defects for pure iron. TDA gave the same results even for the cold-drawn pearlite steel.
