Grain size analysis in titanium
In this example, Clemex Vision system is used to characterize the grain size on an uneven electropolished sample of titanium.
Figure 1. The grain boundaries of this titanium sample, viewed at 200X magnification, are sometimes darker, sometimes lighter gray than the grains themselves. A few filtering operations are required to allow proper segmentation of each grain.
Figure 2. On the left: Grains detected and spread out, maintaining a 2 pixels gap between grains (Zone operation). On the right: Grain boundary network overlaid over the original image.
Clemex solution for Grain size analysis in titanium
Solution
Demonstrate the ability of the Clemex Vision image analyzer to discriminate and measure all grains in the field of view. The methods and operations used are discussed in the report linked at the bottom of this page (click the Download PDF link).
Results
Grain size measurements (ASTM E 112) by objects and by fields were performed. A Length measurement was also performed on each object.
