Back to Solutions Lab Overview

One of the most important microstructural features in alloys is dendrite arm spacing (DAS) as it’s been linked to a variety of mechanical properties, a few being tensile strength, hardness, and corrosion resistance. Being able to easily and consistently measure DAS is therefore incredibly helpful for any analysis of metallic alloys.

To streamline this process, a workflow was created that combined automation through image processing and the ability for manual fine-tuning to ensure both accuracy and speed in finding DAS measurements. 

This type of customizable analysis allows for lean reporting and only includes information of interest.
