Effect of Cooling Time on Fracture Toughness at the Simulated HAZ of DP600 Steels 2004-01-0165
In this study, the Gleeble test was used to investigate the effect of cooling time, which is an indication of welding heat input, on fracture toughness at the simulated HAZ of different test materials, including one mild steel and three DP600 steels from three different suppliers. One of the important findings is that the three DP600 steels have similar tensile properties and similar base metal microstructures. After different simulated welding thermal cycles, however, the microstructure, the microhardness and thus the fracture toughness of the simulated HAZ of the steels showed significant variations among the steels tested, which indicates that DP600 steels from different suppliers can have different responses to the welding heat input.
