Abstract:
Ultrasonic creeping wave testing technique of foils (thickness≤0.5 mm),sheets(thickness 0.5~6 mm) and plates (thickness≥6 mm) is described in this paper.At the same time,ultrasonic creeping wave testing practical examination results and relevant data for TC4 Ti alloy foils with thickness 0.2 mm and Mo alloy plates with thickness 16mm have also given by manual contact method ultrasonic creeping wave testing technique.Besides,ultrasonic creeping wave experimental testing results and relevant data etc for TA2 Ti sheets with thickness 0.5 mm and TC4 Ti alloy plates with thickness 20 mm have also been given by manual contact method ultrasonic creeping wave testing technique.Practical examination results and relevant data etc demonstrated that the ultrasonic creeping wave testing technique for foil,sheet and plate was correct and efficient.
