Abstract:

Additional est results on the modulus of elasticity and creep properties of textured Fe-Si 3 Si sheet reveal a strong effect of ferromagnetism on the elastic and plastic properties. Excellent agreement is obtained between the activation e ergies for creep and self-diffusion if a modulus-compensated creep rate is utilized in the determination of the activation energy for self-diffusion. Similar tests on pure Fe Puron reveal almost identical trends. Dynamic modulus measurements were made on polycry talline Cu grain diameter, L 0.03mm containing a strong preferred orient tion texture and on a randomly oriented polycrystalline s mple. A resonant frequency could not be detected beyond 300 C for the random Cu sample the same difficulty was not encountered with the textured Cu low angle boundaries until about 550 C was reached. These peculiar results were entatively associated with grain boundary relaxation effects. Author
