“…(4) In order to apply the third-generation AHSSs to automotive sheet components, many studies on fatigue strength [6,54,81,[101][102][103], toughness [6,29,43,54,57,81,88,[104][105][106], hydrogen embrittlement resistance [13,18,107,108], and weldability [109][110][111][112][113][114][115][116][117][118][119] will be un-dertaken. It has been reported so far that the partial replacement of Si by Al increases the hydrogen embrittlement resistance in the 0.2C-(0.5-1.5)Si-1.5Mn-(0.04-1.0)Al TBF steel [13].…”

Partial replacement of Si by Al improves the coatability (or galvanizing property) of Si-Mn advanced high-strength steel (AHSS) sheets. In this paper, the effects of the partial replacement on the microstructure, tensile property, and cold formability are reported for the low-carbon third-generation AHSS sheets, which are classified into two groups, “Group I” and “Group II”. The partial replacement by 1.2 mass% Al increases the carbon concentration or mechanical stability of retained austenite and decreases its volume fraction in the AHSSs, compared to Al-free AHSSs. The partial replacement deteriorates the tensile ductility and stretch formability in the AHSSs with a tensile strength above 1.2 GPa. On the other hand, it achieves the same excellent stretch-flangeability as Al-free AHSSs. A complex addition of Al and Nb/Mo further enhances the stretch-flangeability. The cold formabilities are related to the heat treatment condition and microstructural and tensile properties, and the stress state.
