Grains

Posted by:

Using this module you can determine the grain size of a wide variety of materials. Analyses can be performed on materials ranging from steel and nonferrous metals right through to ceramics. It is possible for analyses to be performed in accordance with DIN EN ISO 643, ASTM E 112 or ASTM E 1382. Additional standards are offered by the “Comparison Method”. Depending on your requirements and samples, you can choose from three measurement methods:

  • Automatic grain boundary reconstruction
  • Semi-automatic intercept method
  • Interactive comparison using comparative diagrams

Experienced users can define the measurement procedure in just a few steps. The report can be adapted to your requirements. Once it has been set up, even inexperienced users are then able to operate the system simply and conveniently. You can manage the data in a clearly-structured archive. The test specifications are also saved here, in addition to the reports, images and data tables.

The Automatic Method
This technique detects grain boundaries automatically and analyzes them. Artifacts are removed and grain boundaries reconstructed clearly, even in the case of complex structures. In addition to the average grain size, you can also determine the grain size distribution using this method.

The Chord Method
Using this semi-automatic method, you overlay a measurement grid onto the micrograph. You can choose from various sample grids for this purpose. The module marks the intercept points with the grain boundaries automatically. If necessary, you can add additional intercept points or remove them.

The Comparison Method
Using this interactive method, you can compare the micrograph with comparative diagrams. The Compare method offers the following comparative diagrams:

  • ASTM Plate I
  • ASTM Plate II
  • ASTM Plate III
  • ASTM Plate IV
  • SEP 151061
  • BS 4990
