| 摘要 | The effect of aging temperature on precipitates in AZ80 magnesium alloy was studied by using environmental scanning electron microscope (ESEM) and transmission electron microscope (TEM). The precipitate/matrix orientation relationships (ORs) were measured, the precipitation mechanism was analyzed and the effect of precipitates on properties of alloy was tested. A new precipitated way of granular beta-Mg17Al12 phase was found in aged alloy, which was granular and nucleated at grain boundaries (GBs) and twin boundaries. Plate-like or graunlar-like beta-Mg17Al12 precipitated continuously in the alloy aged at higher temperature (310 degrees C). The plates were parallel to the basal plane of matrix, nucleated and grew homogeneously in grains, and had little effect on properties of alloy. Whereas the granular beta-phase was harmful for the alloy property. The discontinuous precipitation of beta-phase occurred at lower aged temperature (<250 degrees C), which was lamellar structure parallel or perpendicular to the basal plane of matrix, nucleated at grain boundaries and grew into grains. The grain boundaries moved into the grains with the growth of these discontinuous precipitates. The alloy was strengthened by the discontinuous precipitates evidently. |
