Hi mj,
I am a TOFD specialist working over mainly carbon steels. I have tried TOFD application on 18-10 Cr Ni, as everybody knows the metallurgy is very difficult to explain and standardise. Therefore I could not achive a succesfull experimental. However, i have used 1 MHz probes with very low dB, this helps me too much. If you send the details to me via e-mail, Ý will help you.
