中文摘要the influences of trace boron on microstructures and tensile properties of mg-4al-4la-based alloys prepared by cold-chamber high-pressure die-casting method were thoroughly investigated. the results indicated that adding trace boron to mg-4al-4la-based alloy can refine the dendrite arm spacing of primary alpha-mg phases, which are mainly due to the little inoculating alb2 particles. in addition, we found that adding 0.01-0.02 wt.% boron can drastically changes the eutectic morphology, with secondary particle dispersion becoming irregular and eutectic volume fraction being reduced. these phenomena can be attributed to the competitive nucleation between alpha-mg and alb2 particles for al11la3 phases, and to the fact that more al and la atoms saturate into the alpha-mg matrix. considering the tensile properties, although adding 0.01-0.02 wt.% boron decreased the strength of mg-4al-4la-based alloy, adding 0.03 wt.% boron significantly improved the tensile properties due to dispersion strengthening and, to a certain extent, solid-solution strengthening.
