Automated Step Polishing to Identify Features in JetHete Aerospace Alloy Billet

on November 3, 2017

Contact ultrasonic testing (UT) initially flagged a feature in a JetHete alloy billet. Automated step polishing (step size 33 microns) with Robo-Met.3D® was used to identify and characterize the size, location, and orientation of the feature, in relation to the local microstructure. After planarizing, the feature was identified in fewer than 8 steps as a series of pores. No other microstructural anomalies were found near or around the features.

We are grateful to Dr. Graham McIntosh, Jeanne Treasurer, and D. Jay Geibel of Universal Stainless Inc. for the JetHete sample, and collaboration in writing this note.
