~--Frequency and temperature dependency of crack propagation velocity in delayed failure under superposed t~..ating load was analyzed using an internal friction model which assumes the interaction between hydrogen atoms and the cyclic moving of the position with tri-axial tensile stress at crack tip

The relation between diffusion behavior of hydrogen atoms and crack branching in delayed failure was discussed. The hypotheses that diffusion paths of hydrogen atoms at crack tip broaden with increase of stress intensity factor K, and that crack branching occurs when hydrogen atoms diffuse through
