Physical simulation as a tool to understand friction stir processed X80 pipeline steel plate complex microstructures

The thermal cycles associated to friction stir welding and processing produce a wide range of microstructures, resulting in different mechanical behaviors along the weld. Most research efforts have focused on the development of welding parameters to obtain sound welds, yet there is still an opportun...
