DOI: 10.1016/j.jmapro.2021.03.027
Abstract: Abstract Thermally simulated experiments on high-strength weld metals were performed. Based on the results, an extended continuous cooling transformation (CCT) curve with microstructure, hardness, and impact toughness can be proposed. The microstructures, hardness, high-angle grain… read more here.
