A new method for strengthening magnesium (Mg) alloys was invented by Miura et al. A new method is called Deformation Restricted Forging (DRF) processing. In previous study, rotating bending fatigue tests, static tests and EBSD analysis were carried out using two types of Mg alloys, i.e., commercial AZ80Mg and DRF-AZ80Mg alloys. As a result, static strength of DRF-AZ80Mg alloy was improved however the fatigue property was not improved. In this study, fatigue crack propagation (FCP) properties were investigated by replica method using the specimen which have a micro drilled hole. As a result, FCP property was not different between commercial AZ80Mg and DRF-AZ80Mg alloy. Also, fatigue life was not different between commercial AZ80Mg and DRF-AZ80Mg alloy.
