Attenuation Characteristics of Ultrasonic Velocity and Acoustic-Based TC4 Alloy Uniformity Nondestructive Evaluation

Abstract:

ultrasound characteristics of the material microstructure nondestructive evaluation of its experimental sample TC4 titanium alloy microstructure of two-phase microstructure:. Α-phase and α + β phase. Phase material microstructure and grain area ratio directly affects the material uniformity, uniformity of material differences caused by different grain characteristics which ultrasound parameters. Flooding experiments using ultrasonic method for measuring the material longitudinal wave velocity; measuring the sound attenuation coefficient, combined with the area ratio of the sample α using multiple pulse method. Associated with the sample area ratio between the speed of sound and sound attenuation analysis of α-phase titanium alloy TC4 through the material properties of ultrasound to characterize the degree of uniformity of the material microstructure, nondestructive evaluation of materials in order to achieve the purpose of the microstructure.
