Elastic Modulus

I am working on microstructural characterization in metallic materials, such as ferritic steels, Inconel 625 superalloy etc., using ultrasonic measurements. Quite often, I need the elastic modulus values of various types of precipitates for uderstanding the change in ultraosnic velocity with precipitation, such as M23C6, Cr2N, and Fe2Mo (Laves phase) in steels and gamma prime, gamma double prime, delta and Ni2Mo type of precipitates in Superalloys. Is there some publication or record where I can get these values, or if some body can supply these values i will be very much thankful to him.

Thanking You.

Anish Kumar

Re: Elastic Modulus
onic waves directly.
Therefore again my recommendation: You have to measure the velocities on suited samples of your material.

Kind regards
