Embodiment 1
[0043] (1) Design and select the Mg-3Bi-3Sn-2.5Al-1Zn-0.03Ca-0.02Y (wt%) alloy composition ratio to form a magnesium alloy. The preparation method includes the following steps:
[0044] 1) Ingredients: pure Mg (99.8wt%) ingot, pure Bi (99wt%) block, pure Sn (99wt%) block, pure Al (99.9wt%) block, pure Zn block (99wt%), Mg-20Ca and Mg-30Y master alloy is used as raw material, after surface pretreatment (such as removal of dirt, scale, etc., the same as in the following examples), the ingredients are formulated according to the above target components; mass ratio Bi:Sn=1:1;
[0045] 2) Melting: Clean and preheat the crucible, put the magnesium ingot preheated to 200°C into the crucible of the melting furnace, set the furnace temperature to 720°C, and heat slowly at a heating rate of 25°C / min. After it melts, add the pure Bi block preheated to 50°C, the pure Sn block, the pure Zn block, the pure Al block preheated to 200°C, the Mg-Ca master alloy and the Mg-Y master alloy into th...
