Grain Determination |
| |
Conforming to Standards |
| |
Determine grain sizes according to ISO, ASTM or EN standards using automatic grain boundary reconstruction, chord length or chart comparison.
|
 | | Microscope based measurements |
| The Grains module is integrated into AxioVision directly as an application, therefore expanding its functionality to include grain size analysis. The user is guided through the process step by step: from selecting the measurement method and measuring the grain size to archiving and drawing up a report. |

| With the AxioVision Grains module, three measurement methods are available for measuring grain sizes according to industry standards.
• Flexible measurement methods
• Analysis according to standards (ISO, ASTM, EN)
• Convenient data archiving |
 | | Automatic Measurements |
| The automatic method offers automatic reconstruction of grain boundaries and can be used for e.g. ferritic steels, ceramics, hard metals and aluminum surfaces. This method calculates not just the average grain size but also the distribution of grain sizes. |
 | | Semi-Automated Measurements |
| The semi-automatic method uses the intercept approach, where a mask of lines and circles is overlaid onto the sample image. The grain boundary intercepts are located automatically and can be corrected by adding or deleting. The calculation of the grain size is based on the standardized chord length measurement. |
 | | Interactive Measurements |
| The interactive method represents a simple alternative. It is based on a conventional comparison of the sample with industry reference tables. The advantage offered by image analysis is the possibility of overlaying the image for comparison from the reference series directly onto the image of the sample. |
