Microstructure- and Strain Rate-Dependent Tensile Behavior of Fiber Laser-Welded DP980 Steel Joint

Journal of Materials Engineering and Performance February 2016, Volume 25, Issue 2, pp 668-676 Qiang Jia (1), Wei Guo (1), Peng Peng (1) (2), Minggao Li (3), Ying Zhu (1), Guisheng Zou (4)   Abstract DP980 steels were butt-welded by fiber laser welding. The microstructures, microhardness distribution, and tensile behavior of the joint were investigated. The results showed that the fusion …
