摘要：

The deformation behavior of AZ91D cast magnesium alloy was investigated using uniaxial tensile tests from room temperature up to 190 degrees C and strain rates from 0.0001 up to 0.1 1/s. In present work gradient solidification in a Bridgeman furnace was employed to study the effect of initial microstructure on the tensile mechanical response of the AZ91D alloy. The furnace drawing rate was varied from minimum 0.3 to maximum 6 mm/s, which yielded a variation of SDAS from 4.2 up to 25 as well as a variation of the fraction of the gamma-phase (Mg17Al12),. The effects of microstructural parameters such as SDAS and gamma-phase morphology on the yield strength (YS), ultimate tensile strength (UTS) and hardening were investigated.
