| description | The invention provides a method for predicting microstructure change of a near-alpha type titanium alloy aviation die forging. The method comprises the following steps: S1, measuring microstructures of a material under different process conditions; S2, carrying out statistical analysis on the microstructure of the core part of the test piece under different treatment processes, especially the content change of a primary alpha phase; S3, establishing a prediction model of primary alpha phase change; S4, performing a die forging test; and S5, based on the prediction model of the primary alpha-phase change, realizing visual prediction of the microstructure change of the near-alpha titanium alloy die forging through finite element numerical simulation analysis. According to the method for predicting the microstructure change of the near-alpha type titanium alloy aviation die forging, the distribution rule of the primary alpha phase of the near-alpha titanium alloy blank after high-temperature die forging and the |
