AB  - In order to reduce the thermal stress in high chromium cast iron (HCCI) matrix 
      composites reinforced by zirconia toughened alumina (ZTA) ceramic particles, 
      finite element simulation is performed to optimize the geometric configuration of 
      ceramics perform. The previous model simplifies the overall structure of the 
      ceramic particle preform and adds boundary conditions to simulate the particles, 
      which will cause uncontrollable error in the results. In this work, the 
      equivalent grain models are used to describe the actual preform, making the 
      simulation results closer to the actual experimental results. The solidification 
      process of composite material is simulated, and the infiltration between molten 
      iron and ceramic particles is realized. Thermal stress in solidification process 
      and compression stress distribution are obtained. The results show that adding 
      10-mm round holes on the preform can improve the performance of the composite, 
      which is helpful to prevent the cracks and increases the plasticity of the 
      material.
