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.

AgCuOSnO2 复合材料的表征/机械行为：实验和有限元研究

在此， 通过有限元分析研究了不同含量的 SnO ₂对 AgCuO(10)SnO ₂ ( x = 2,5,8) 复合材料在热挤压过程中的应力、应变和微观结构的影响，并进行了比较。与实际的热挤压实验。结果表明，立方CuO在热挤压过程中主要由于剪切应变而逐渐变成纤维状，而单斜CuO和SnO ₂仅产生轻微变形。热挤压后，强化相CuO和SnO ₂重新分布，使显微组织更加均匀，与实际实验结果吻合较好。此外，通过比较不同SnO ₂含量的样品的力学性能,当SnO ₂含量为5%时，AgCuOSnO ₂具有最高的电导率、应变和抗拉强度。
