声发射检测 材料或构件因受力产生变形或断裂，以弹性波的形式释放出应变能称为声发射。利用接收声发射信号研究材料、动态评价结构的完整性称为声发射检测技术。声发射技术是1950年由德国人凯泽(J.Kaiser)开始研究的，1964年美国应用于检验产品质量，从此获得迅速发展。声发射检测的基本原理见图。材料的范性形变、马氏体相变、裂纹扩展、应力腐蚀以及焊接过程产生裂纹和飞溅等，都有声发射现象，检测到声发射信号，就可以连续监视材料内部变化的整个过程。因此，声发射检测是一种动态无损检测方法。 声发射检测仪器分单通道和多通道两种。单通道声发射仪比较简单，主要用于实验室材料试验。多通道声发射仪是大型声发射检测仪器，有很多个检测通道，可以确定声发射源位置，根据来自各个声源的声发射信号强度，判断声源的活动性，实时评价大型构件的安全性。主要用于大型构件的现场试验。 声发射技术的应用已较广泛。可以用声发射鉴定不同范性变形的类型，研究断裂过程并区分断裂方式，检测出小于 0.01mm长的裂纹扩展,研究应力腐蚀断裂和氢脆，检测马氏体相变，评价表面化学热处理渗层的脆性，以及监视焊后裂纹产生和扩展等等。在工业生产中，声发射技术已用于压力容器、锅炉、管道和火箭发动机壳体等大型构件的水压检验，评定缺陷的危险性等级，作出实时报警。在生产过程中，用声发射技术可以连续监视高压容器、核反应堆容器和海底采油装置等构件的完整性。声发射技术还应用于测量固体火箭发动机火药的燃烧速度和研究燃烧过程，检测渗漏，研究岩石的断裂，监视矿井的崩塌，并预报矿井的安全性。
