摘要：

The experimental study of aluminium alloys based on the Al-Ca-Zn-Mg system (3.5% Mg and 2.5% Mg, 0-10% Ca, 0-14% Zn (wt-%)) was combined with Thermo-Calc simulations for the optimisation of the alloy composition. Zinc is distributed between aluminium solid solution and phase (Al,Zn)(4)Ca. Magnesium was not observed in the intermetallic phase. The eutectic (Al,Zn)(4)Ca had fine structure and particles of (Al,Zn)(4)Ca were capable of spheroidisation during the heat treatment at 520 degrees C. The maximum level of hardness observed in calcium-containing alloys was higher than 200 HB, suggesting good strength properties. With an example of the Al-Zn (9%)-Mg(3.5%)-Ca(3%) alloy, the possibility of manufacturing thin rolled sheets based on the (Al)-Ca eutectic was demonstrated.
