Effect of In-Situ Reinforced Particle on the Failure of TiC/AZ91 Composites

By using image processing, recognition technology and edge extraction technology, the true particle morphology and distribution of TiC / AZ91 composites were obtained, and finite element numerical calculation models of different particle shapes were established. with the help of ansys finite element software, the stress distribution and maximum strain values of TiC/AZ91 composite under different enhanced particle shapes are studied to explore the influence law and mechanism of the material on the failure behavior of the material. The results show that, compared with round particles, square particles are prone to plastic damage and lead to the destruction of magnesium-based composites.
