Characterization/mechanical behavior of AgCuOSnO₂ composites: Experimental and finite element study

Abstract Herein, the effects of different content of SnO₂ on the stress, strain, and microstructure of AgCuO(10)SnO₂(x = 2,5,8) composites during hot extrusion were studied by using finite element analysis and compared with the actual hot extrusion experiment. The results show that cubic CuO gradually becomes fibrous mainly due to shear strain during hot extrusion, but monoclinic CuO and SnO₂ only produce slight deformation. After hot extrusion, the reinforced phases CuO and SnO₂ are redistributed to make the microstructure more uniform, which is in good agreement with the actual experimental results. In addition, by comparing the mechanical properties of samples with different content of SnO₂, when the SnO₂ content is 5%, AgCuOSnO₂ has the highest conductivity, strain, and tensile strength.
