Abstract
As the melted iron and zirconia toughened alumina particles are non-invasive, it is always a critical problem to realize the infiltration between melted iron and ceramic particles. The solidification process of high chromium cast iron matrix composites reinforced by zirconia toughened alumina ceramic particles by infiltration casting is simulated using finite element analysis method in this paper. Two physical modules, heat transfer in solid and solid mechanics are used to describe the solidification phenomenon. The variation and distribution of stress field and temperature field during solidification are analyzed. By comparing the stress of different diameter/wall thickness ratio, the optimal diameter/wall thickness ratio for performance is found to be 1.5 to realize the infiltration process. Compared with the experimental results, it shows that the simulation results are in accordance with the experiments results, so the established model and simulation methods are correct, and can provide the foundation for the further research.
