Abstract: Rotating bending fatigue tests have been performed using smooth specimens of a rolled AZ31 magnesium alloy in laboratory air at ambient temperature. Fatigue strength and characteristic was evaluated and fracture mechanism was discussed on the basis fracture surface analysis. Electrical polishing (EP) as well as deep rolling (ball burnishing (BB)) U-notched specimens were performed on ...

Magnesium alloys are still the focus of current research. Special importance is attached to economic production semi-finished magnesium products, for example flat products. In past 20 years, twin-roll-casting alloy strips has been intensively investigated at Institute Metal Forming and successfully applied various compositions (from AZ31 ZAX210 WE43). The TRC technology enables providing a wide...
