Abstract

Abstract The microstructure of materials introduced by rolling, drawing, heat treatment or other methods of material processing relates to the macroscopic mechanical properties of the materials, such as the strength and anisotropy. The velocity and attenuation of the ultrasonic waves propagating in the materials are known to be dependent upon such microstructural material properties. The author has proposed a theoretical modeling of an ultrasonic nondestructive method to evaluate the microstructural property changes of materials in Part I of this work. In the present paper, annealed effects on plastically deformed states of an aluminium alloy were studied using the proposed ultrasonic nondestructive evaluation method and it was found that close agreement between the simulated results and experimental data was possible.
