I am trying to find the acoustic longitudinal velocity for Inconel 825. there is not much information posted about this alloy. Does any one have any ideas what the velocity is or where I might find it?

John:

Velocity V=D/t Two techniques: (1) Find a place with known thickness (t) such as flange. Using your UT to find the transient time ( delta T). The time from initial pauls to first back wall or the transient time from 1st back wall to 2nd back wall.

V= 2 x thickness/ delta T

(2) Find a place with known thickness (t) such as flange. Using your UT, placed a probe on the known thickness area and change the velocity until the first back to the correct thickness.

You can find a table of acoustic velocities in Part 2 of the NDT Handbook,UT testing,Volume Seven from ASNT. It shows the longitudinal wave velocity as 5820 m/s for Inconel.
