Abstract
Measurements of ultrasonic velocity and attenuation can provide important tools in characterizing the microstructure of materials [1]. For example, velocity measurements can provide information on crystallographic texture while attenuation measurements provide information of grain size. For selected cases, a strong theoretical base is in place [2–4]. However, when both texture is present and the grains are elongated, such is not the case. The purpose of this paper is to describe theoretical calculations addressing this problem. Aluminum is chosen as the material because of interests in using ultrasound to monitor its recrystallization [5].
