Preparation and detection method of compression sample of hard α inclusion material in titanium alloy |
| abstract |
The invention relates to the field of titanium alloy material preparation, in particular to a preparation and detection method of a compression sample of a hard alpha inclusion material in a titanium alloy. The method includes the following steps: (1) using hot isostatic pressing technology to prepare TiN inclusion block materials with different nitrogen contents; (2) processing cylindrical compression samples by wire cutting; (3) preparing nitrogen content below 12wt% Compression samples; (4) Use a high-temperature compression testing machine to test the compression properties. The test temperature is 900°C to 1100°C and the strain rate is 0.01S -1 to 10S -1 . Therefore, it is possible to accurately detect the thermal deformation characteristic data of TiN materials with different nitrogen contents, break through the key technology of preparation and detection of compression samples of TiN inclusion materials, and solve the "stuck neck" problem of my country's independent airworthiness system. |
