The researchers have shown that structural faults in carbon steel make it absorb sound very effectively at a certain point in its life. The non-contact technique is based on the effect of this absorption on a magnetic field, and could be used to monitor the condition of axles in trains and motor vehicles.<br \/>\n<!--more--><br \/>\nRead the <a HREF=\"http:\/\/physicsweb.org\/article\/news\/6\/2\/15\">full story<\/a> on the Physics Web site.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Japanese researchers have found a way of predicting the remaining lifetime of stressed steel.
