摘　　要：采用商业有限元软件DEFORM3DTM对半固态镁合金AZ91D的触变成形过程进行了数值模拟,并利用自制的模具,在加热到570℃保温不同时间的情况下,对AZ91D镁合金半固态坯料进行触变成形试验。通过模拟分析的结果与试验的实际结果进行对比,得出了最佳触变成形工艺参数,同时,在一定程度上验证了数值模拟分析结果的可靠性。The author of this paper using the commercial Finite element software DEFORM3DTM, for the simulation of deformation in the semi solid state magnesium alloy AZ91D. This paper used home-made mould to test thixo-processing property of AZ91D magnesium alloys at 570℃ with different holding time. Simulation results are compared with experimental results, the optimal thixoforming processing parameters were obtained, and the dependability of numerical simulation results were validated at certain extant.
