...Farhang Farrokhi; Benny Endelt; Rasmus S. Andersen; Morten Kristiansen Grain refinement and the avoidance of columnar solidification is a great challenge in the deep penetration laser welds of thick-section steels. Further knowledge about the heat distribution and the temperature gradients in laser...

... hole of hardened carbon steels, which results from two mechanisms: thermally driven phase transformation and mechanical grain refinement due to severe plastic deformation. In this study, a multistep numerical analysis is conducted to investigate the potential mechanism of surface microstructure...

.... In this paper, a finite element based numerical framework embedded with a dislocation density-based material plasticity model was developed to simulate steady-state chip formation, grain refinement and microstructural evolution of the dislocation cell structure by orthogonal cutting. The validity...
