Imaging of modified 9Cr–1Mo ferritic steel weldment via ultrasonic velocity measurements

摘要: Abstract Ultrasonic velocity measurements have been carried out across the weld line in two perpendicular sections of modified 9Cr–1Mo ferritic steel weldments, as welded and post-weld heat treated (PWHT) conditions. The ultrasonic plot is correlated with profile both associated microstructural features different regions weldments for conditions investigated. present study reveals that can be imaged adequacy PWHT also assessed using measurements.
