The Role of κ-Carbides as Hydrogen Traps in High-Mn Steels

The Role of κ-Carbides as Hydrogen Traps in High-Mn Steels

Since the addition of Al to high-Mn steels is known to reduce their sensitivity to hydrogen-induced delayed fracture, we investigate possible trapping effects connected to the presence of Al in the grain interior employing density-functional theory (DFT). The role of Al-based precipitates is also in...
