Abstract

The microstructure and mechanical properties of AZ61- 1Sm magnesium alloy with Sb addition were analyzed by X-ray diffraction (XRD), light optical microscopy (OM), and scanning electron microscopy(SEM). The results demonstrate that addition of 0.5wt.%Sb to the AZ61-1Sm alloy obtains the highest ultimate tensile strength (UTS) after subsequent aging, and improves the elongation of the alloy, especially at the elevated temperature. The microstructure showed a typical non-equilibrium cast structure consisting mainly of -Mg matrix, eutectic compounds and some dispersive precipitates. Precipitation behavior of second phase particles and their effects on the strengthening mechanisms were investigated. The pronounced second phase particles are spherical and distributed dispersedly in grains and grain boundaries. The fracture mode changes from transgranular to micro-void coalescence fracture with increasing the temperature to 175 .
