Embodiment 1
[0015] A beryllium-containing and dual-phase α+β magnesium-lithium alloy. According to the weight ratio, the composition of the alloy is: Li: 9.2wt.%, Be: 0.2wt.%, Sb: 1.3wt.%, Cr: 0.3wt.%, V: 0.1wt.%, Pb: 0.3wt. %, Se: 0.2wt.%, the balance is magnesium. The preparation method of the alloy: add the above-mentioned raw materials into an induction furnace protected by argon gas, and use a silicon carbide crucible. Inductively heat to 750 degrees to form an alloy solution, and use the electromagnetic stirring effect to fully stir for about 10 minutes. The alloy liquid is kept at 750 degrees for 10 minutes and then cast into water glass or graphite molds for casting. The ingot was subjected to deformation treatment at room temperature, and the rolling reduction in each pass was 25%. Every 3 passes of rolling requires an intermediate heat treatment to eliminate work hardening. The process is: 300 degrees for 1 hour. The final heat treatment process after rolling is: vacuum solu...
