中文摘要：

使用反应合成法制备了AgSnO2材料，对材料的加工性能进行了分析。经断裂拉伸测试和分析表明，AgSnO2材料的拉伸断口微观形貌由台阶组成；而随着SnO2质量分数的增加，AgSnO2材料的硬度提高，延伸率降低；随着真应变的增加，材料的延伸率增大。采用有限元方法，对AgSnO2材料的挤压过程进行模拟仿真，分析AgSnO2材料在整个挤压过程中的应力应变情况，研究结果对解决颗粒增强金属基复合材料难加工的问题具有重要的指导作用。

英文摘要：

AgSnO2 composites were prepared by the reactive synthesis and analyzed. The SEM fractographs of the tensile specimens indicate that the the workability of AgSnO2 was fracture morphology consists of many sidesteps. The hardness of AgSnO2 increases and the elongation decreases with SnO2 increasing. With the true strain increasing, the elongation of AgSnO2 increases. The finite element simulation method was used to simulate the extrusion process of AgSnO2. The stress and strain in this process were analyzed. The results will play an important role in solving practical production problems.
