Extract

X-ray fractography was applied to the fatigue fracture surface of ZAS (Zinc Alloy for Stamping) alloy, which has composite microstructures: Zn-phase, Al-phase and Zn-Cu phase. The fatigue test was conducted by using compact tension specimens. Residual stresses were measured on and beneath fatigue fracture surfaces. The plastic zone size was determined from residual stress distributions beneath the fatigue fracture surfaces. The results are discussed in connection with fracture mechanics and fracture processes.
