Microstructures and failure analyses of DP980 laser welded blanks in formability context
Abstract
In the present study, Erichsen cup height and limiting drawing ratio of fiber laser welded DP980 blanks were compared with respect to that of parent metal to understand the role of deformation mode in formability context. The strain localization was observed consistently at the outer heat affected zone (HAZ) during both the tests in laser welded blanks with failure propagated in radial direction and parallel to the weld. The microstructure …
