前言声发射技术是在六十年代发展起来的一种评价材料的新方法。早在五十年代初期,德国的卡塞尔首先在金属材料的研究中利用了这项技术,发现金属在拉伸和相变过程中发出噪声。当时由于各方面的原因,工作进展较为缓慢。进入六十年代之后,由于宇宙航行,原子能,航空等国防工业的发展,使声发射技术得到重视,应用范围日益扩大。

Introduction Acoustic emission technology is a new method of evaluating materials developed in the sixties. As early as the early 1950s, Kassel, Germany first used this technique in the study of metallic materials and found that the metal was noisy during the stretching and transformation. At that time, due to various reasons, the progress of work was slower. Since the 1960s, due to the development of defense industries such as astronautics, atomic energy and aviation, the acoustic emission technology has been taken seriously and its application scope has been expanding.
