Fatigue Test of Small Sized AZ31 Magnesium Alloy Using Micropillar Specimen

Abstract:

The bending fatigue tests were performed using the small sized specimens of AZ31 magnesium alloy fabricated by the focused ion beam (FIB) processing to investigate the scale effect on the fatigue behavior. For the fatigue test of the small sized specimens, the fatigue testing apparatus was constructed by the piezo actuator and the high-resolution microscope for controlling the very small displacement. The specimen was micropillar-shaped with the rectangular cross section of 3μm x 8μm and the height of 40μm. The fatigue strengths of the small sized specimens were higher than those of the bulk sized specimens. The fracture surfaces were also investigated carefully compared with those of the bulk specimen.
