Ultrasonic Materials Characterization
Abstract
Nondestructive testing involves a search for flaws in materials or structures; it is appreciated that voids, cracks, inclusions, and similar flaws can lead to failure. Once a flaw has been detected, it is natural to consider methods that will give more information. What is the flaw size, type, location, or orientation? It is recognized that parameters such as hardness, grain size, bonding, and residual stress can have a strong influence on material performance. The use of ultrasonic nondestructive testing to characterize materials both in terms of properties and flaws is described.
