Ultrasonic testing is a non-destructive method that can be used to detect, locate and size flaws. The purpose of this paper is to review techniques that utilise ultrasonic bulk waves to size flaws. Flaws that are embedded within a component (i.e. remote from any surface) as well as flaws growing from inaccessible surfaces are considered. The different available techniques are grouped into the following categories: amplitude, temporal, imaging and inversion. The principles, applications and limitations of the different techniques are covered, as well as approaches to assessing the performance of the techniques. Finally, remaining gaps and challenges in sizing flaws, particularly in an industrial setting, are discussed.
超声检测是一种无损检测方法，可用于检测、定位和定量缺陷。本文旨在综述利用超声波体波定量缺陷的技术。所考虑的缺陷位于构件内部（即远离任何表面）以及从不可接近表面生长的缺陷。不同的可用技术可分为以下几类：幅度、时间、成像和反演。涵盖了不同技术的原理、应用和局限性，以及评估技术性能的方法。最后，讨论了在工业环境中特别是在定量缺陷方面仍然存在的差距和挑战。
