本文以大量试验实例说明,对钛合金超声检测中的杂波水平要求是完全必要的。它不仅为保证超声检测时的信噪比所需要,而耳其本身又是表征钛合金显微组织均匀性及形貌的重要参数。本文还对杂波水平的定义及其评定方法阐述了作者的观点。
In this paper, a large number of experimental examples show that the ultrasonic testing of titanium alloy in the level of clutter is completely necessary. It is not only necessary for ensuring the signal-noise ratio of ultrasonic testing, but also is an important parameter for characterizing the uniformity and topography of titanium alloy microstructure. This article also expounds the author’s point of view on the definition of clutter and its assessment method.
