Paper Title:
Low-Cycle Fatigue Behavior of Three Die Cast Magnesium Alloys
  Abstract

Totally strain-controlled low cycle fatigue tests with a strain ratio Rε= -1 were carried out on die-cast AZ91HP, AM50HP and AE 42 alloys at a constant strain rate of 2.5×10-3 s-1 and room temperature. The cyclic deformation behavior of the three alloys was investigated through the characteristics of representative hysteresis loops at various total strain amplitudes. Cyclic deformation hardening was observed and the low-cycle fatigue life data were analyzed using the well known Basquin and Coffin-Manson equations. The transition life of the three alloys is considerably low, which can be attributed to the low ductility of these die cast Mg alloys.
