Grain Size in Martensitic Steel
One martensitic stainless steel image is submitted for analysis. The absence of clear grain boundaries makes martensitic structures difficult to segment using traditional threshold-based methods. A machine-learning algorithm specifically developed for martensitic steel allows a reproducible one-step detection.
