Development of a mathematical model for propagation of ultrasonic waves in thick-walled cylinders in the presence of a thermal gradient - Case of axial scanning

R. Shabani et al.

Summary: Investigation of ultrasonic wave velocity and travel path variations in the presence of thermal gradients in thick-walled hollow cylinders is important for accurate ultrasonic testing of engineering components subjected to high temperatures. A mathematical model was developed and an experimental setup was built to study this phenomenon, with preliminary results showing good agreement between theory and practice.

Monitoring saltwater corrosion of steel using ultrasonic coda wave with control

Maxime Farin et al.

Summary: This paper presents a novel ultrasonic method based on coda wave interferometry to detect and quantify thickness loss caused by saltwater corrosion of steel samples. The experimental results demonstrate that the method has high accuracy and sensitivity, and can provide real-time monitoring of corrosion spread and rate.
