In situ EBSD observation of grain boundary character distribution evolution during thermomechanical process used for grain boundary engineering of 304 austenitic stainless steel
TL;DR: In this paper, electron backscatter diffraction (EBSD) was used to examine the microstructural evolution in a one-step thermomechanically processed 304 austenitic stainless steel specimen during the grain boundary engineering.
Journal ArticleDOI
Friction stir spot welding of single-crystal austenitic stainless steel
Journal ArticleDOI
Microstructural evolution of pure copper during friction-stir welding
TL;DR: In this paper, the microstructural evolution of pure copper during friction-stir welding was found to be principally influenced by welding temperature, leading to significant grain refinement and related material strengthening in the stir zone.
Journal ArticleDOI
High-strain-rate deformation in ultrasonic additive manufacturing
TL;DR: In this article, high-strain-rate deformation in ultrasonic additive manufacturing was analyzed by performing microstructural characterization via electron microscopy, and the micro-asperities on the top tape surface, which were formed by contact with the sonotrode surface, underwent cyclic deformation at high strain rates during welding with an additional tape.
Journal ArticleDOI
Effect of contamination on microstructure in friction stir spot welded DP590 steel
TL;DR: In this paper, the effect of contamination on the microstructure during FSSW of DP590 steel was examined using both bare and TiC/TiN coated Si3N4 tool with Ar shielding.
