Nondestructive evaluation (NDE) by ultrasound offers a wide variety of techniques for materials characterization. Being volumetric in nature, ultrasonic examination can give an idea about bulk material properties. Ultrasonic parameters are significantly affected by changes in microstructural or mechanical material properties. Ultrasonic material characterization has also been used to qualify various processing treatments like precipitation hardening, case hardening, rolling texture, etc. and to assess the damage of metallic components due to various degradation mechanisms like fatigue, creep, corrosion and embrittlement. Ultrasonic techniques for material characteriaztion cover a very wide field of applications in metallic and nonmetallic solid materials, gases and fluids. This chapter deals with applications of metal alloys.
