Abstract
In-situ monitoring of the condition of materials has the potential for reducing the risk of failures, improving maintenance scheduling and costs, and allowing predictions of component life. Stress-corrosion cracks have been shown to emit acoustic signals, and correlations between crack area and the number of acoustic emission events have been developed in laboratory tests. On-line monitoring will require the ability to discriminate between background and crack growth signals. Acoustic emission characteristics such as event rate, amplitude and rise time can be used to discriminate between valid and invalid events. A summary of acoustic emission from stress-corrosion cracking initiation and long crack growth, acoustic emission characteristics, and potential applications is given in this article.
