According to the theory of densification of hot isostatic pressing, a mathematical model of hot isostatic pressing was established, and the computer simulation of the mathematical model was realized. The computer calculation, drawing and analysis of the hot isostatic pressing diagram were completed. The hot isostatic pressing diagram of 3Y-TZP was experimentally verified, the experimental results are in good agreement with the theoretical calculation results. The hot isostatic parameter optimization problem is discussed using the hot isostatic diagram.
