Abstract Scope |
In this work the influence of heat treatment on the stretch formability of an age-hardenable Mg-Al-Ca-Mn-Zn alloy sheet is investigated utilising Erichsen cupping tests within a temperature range from room temperature to 200°C. In contrast to traditional age-hardenable materials, such as Aluminium 6000 series sheets, the results show a lower stretch formability for the solution treated (T4) than for the peak aged (T6) condition, especially at intermediate temperatures (100-200°C). Uniaxial tensile tests reveal a significantly lower strain-rate sensitivity in the T4-condition within the same intermediate elevated temperature regime. These results have a direct implication on an envisioned industrial processing route such that forming of lightweight components should preferably be carried out on peak aged (T6) blanks. |
