A prediction method of near alpha alpha titanium alloy low-power coarse grain structure distribution

The invention relates to a prediction method of near alpha titanium alloy low-power coarse grain structure distribution. The prediction method comprises the following steps of S1 determining the structure of a material under a selected process condition; S2 carrying out statistical analysis on the microscopic structure of the core of the thermal compression test piece under the corresponding process, and carrying out statistical analysis on the grain size; S3 establishing a quantitative prediction model of the original grain size; and S4 on the basis of microscopic structure critical conditionD beta>=D0 formed by the low-power coarse crystals, realizing the visual prediction of near alpha-titanium alloy low-power coarse crystal distribution through secondary development and numerical simulation analysis of finite element software. The prediction method for the macroscopic structure distribution of the near alpha-titanium alloy can effectively reveal the microscopic structure change ofthe near alpha-titanium alloy forge piece after forging heat treatment, and particularly realizes visual prediction of the original grain coarsening and the macroscopic structure distribution causedby the original grain coarsening. The forming process is optimized, the low-power coarse grain area is reduced, and the prediction result is accurate.
