In order to investigate the threshold condition for propagation of Mode I micro fatigue cracks in an aged cracked specimen made of carbon steel, both the stress concentration factors α_<op> and α_<cl> at the micro region of the annealed crack tip, resulting from crack opening and closing respectively, and α_<cl>* at the aged crack tip are adopted. Models for estimating the stress amplitude acting on the micro region near the crack tip are proposed applying the values mentioned above. The stress condition at the crack propagation threshold can be explained by a model using α_<op> and α_<cl>*.
