GRAIN SIZE INSPECTION OF A GAS TURBINE COMPONENT BY X-RAY REFRACTION |
| 摘要 |
A system and method for inspecting a grain size of a cast alloy component while maintaining the structural integrity of the cast alloy component is disclosed. The method includes recording a radiographic image of the component, identifying areas of the component to be inspected, and locating one or more lines having a pre-determined length on the radiographic image at an area to be inspected. Then, a total number of intersections with the one or more lines are determined and an average grain size is calculated. |

1. A method of inspecting a grain size of a cast alloy component while maintaining the structural integrity of the cast alloy component comprising:
recording a radiographic image of the component; identifying areas of the component to be inspected; locating one or more lines having a pre-determined length on the radiographic image at one of the areas to be inspected; calculating a total number of intersections of grain boundaries with the one or more lines; and calculating an average grain size. |
