Abstract Numerical simulation analysis was conducted on the hot isostatic pressing of titanium alloy powder to form impeller discs. The distribution of equivalent plastic strain and the variation of node density over time, as well as the distribution of relative density of pressed parts were studied, and impeller disc samples were prepared using hot isostatic pressing technology. The results show that the numerical simulation results show good consistency with the experimental data. This discovery fully demonstrates the effectiveness of numerical simulation technology in the hot isostatic pressing process of impeller discs, and the accuracy of predicting the forming characteristics. This not only provides strong data support for optimizing the production process of impeller discs, but also lays a solid foundation for the subsequent prediction of complex parts.
