We developed four high-strength A-Mg-Si alloys; to increase comparability, the Mg/Si ratio, as well as Mn, Cu, and Zr contents were held constant. The influence of total Mg+Si content and Zn/Cr additions were studied. All alloys were cast, homogenized, both rolled and extruded, and artificially aged in the same way to ensure reproducibility. Microstructural investigations, differential scanning calorimetry, tensile testing, and welding experiments were performed. Yield strengths up to ~380 MPa and excellent weldability were achieved. Ongoing investigations aim to optimize the artificial ageing response and elucidate the strengthening mechanisms at play.
