Grundlegende Untersuchungen zur orts- und zeitaufgelösten zerstörungsfreien Bestimmung mikrostruktureller Eigenschaften
Abstract
With the help of new multi-parameter sensors, produkt characteristics are evaluated wich otherwise could only be determined so far by time-consuming and cost-intensive testing. By combining complementary information about various physical properties which can be measured by electromagnetic techniques, a fast determination of hardness, strength and residual stress values can be achieved by using multiple regression or neural net analysis. After a calibration procedure 3MA testing unit indicates up to two parameters simultaneously. Results obtained on different laser welded steel sheets have shown that they are in good accordance to conventional tests.
