説明
The low-alloy cast steels, which have the same chemical composition show three types of microstructures, i. e. bainitic structure (material SNA), pearlitic structure (material SNB) and mixed structure (material SNC) by changing heat treatment conditions. The authors have been investigated by the rotating bending fatigue tests and have been observed on the specimen's surface for fatigue crack initiation by the successive-taken replica method and fracture surface with SEM. The main experimental results are shown as follows ; (1) The fatigue limits of SNA, SNB, SNC and SNCs were 430, 225, 270 and 300 MPa, respectively. (2) The fatigue cracks of all specimens initiate at the blow holes, SNB, SNC, SNCs and SNA showed aspect of ductile fracture and brittle fracture on fracture surface. (3) The fatigue limit of experimental data becomes higher than that of the estimated values by Murakami et al's eq.
