摘要
对两种制备工艺制备的SnO2质量分数为5%的Ag/SnO2复合材料进行了不同应变程度的挤压,研究了组织形貌,发现对于反应合成制备的Ag/SnO2材料经过较大真实应变挤压后纤维状组织消失,SnO2颗粒更加弥散。比较了两种方法制备的Ag/SnO2材料的电导率、抗拉强度及延伸率,及质量分数对其的性能的影响。发现经过较大的真实应变挤压,3种性能都得到了很好改善。
In this paper, Ag/SnO2 composite were fabricated by two methods and extruclecl via three stratus. By the observation on the microstructures, it is found that after extruded via larger strain, the fibrous microstructure fabricated by reactive synthesis method disappeared and the dispersion of the particles of SnO2 was further obvious. The influences of the fabricated method and the content of SnO2 on electricity, tensile strength and elong ratio of the composites produced by two different methods were compared. These three performances are improved by larger strain extrusion.
