    采用有限元模擬技術(shù)對反應(yīng)合成的AgSnO2和AgCuO復(fù)合材料的大塑性變形過程進行模擬,研究在不同真應(yīng)變條件下,AgSnO2和AgCuO復(fù)合材料顯微組織均勻化的程度.結(jié)果表明:根據(jù)反應(yīng)合成AgMeO復(fù)合材料燒結(jié)態(tài)組織特點所建立的有限元模型能夠?qū)Υ笏苄宰冃芜^程進行有效模擬,模擬結(jié)果與實驗結(jié)果吻合較好:模擬與實驗結(jié)果表明,反應(yīng)合成AgMeO復(fù)合材料在擠壓過程中不可避免地發(fā)生增強相偏聚的組織分層現(xiàn)象,需要采用更大的變形強度來實現(xiàn)顯微組織均勻化.

    Abstract:

    The finite element simulation was adopted for severe plastic deformation of reactive synthesis AgMeO composites. The homogenization degree of microstructure was researched by simulation and experiment in same true strain condition for AgSnO2 and AgCuO composites. The results showed that the model of finite element, according to the sinter microstructure of AgMeO composites, can effectively simulate the program of severe plastic deformation. The results of simulation and experiment were consistent. From the result of simulation and experiment, the phenomena of microstructure delaminating was inevitable due to the clustering of reinforce phase in the deformation. The homogenization of microstructure can be obtained through the bigger deformation strength.
