X-ray diffraction observation of fracture surfaces provides fracture analysis with useful information on the mechanisms and mechanical conditions of fracturing. This method is called ” X-ray fractography “ and has been developed especially in Japan as a new engineering tool for fracture analysis.In the present paper, X-ray fractography is applied to fatigue fracture surfaces of AZ91 magnesium alloy which are used for machine parts. The X-ray stress constant, H,was first determined. The fatigue tests were conducted by using compact tension ( CT ) specimens of AZ91 magnesium alloy. The residual stress was measured on and beneath the fatigue fracture surface. The depth of the plastic zone left on the fatigue fracture surface was evaluated from the residual stress distribution. The results are discussed on the basis of fracture mechanics.
