Microstructures and properties of a Mg-Li-Al-Zn wrought alloy

  • A novel β base Mg-Li-Al-Zn wrought alloy was designed according as the Mg-Li binary phase diagram and effect of Al, Zn on the alloys. The microstructure and alloy phases changes of the alloy on the states of casting, forging, rolling and rolling-annealing were systematically investigated by optical microscope and X-Ray. The results show that the microstructure of as rolling-annealing is satisfying. The results from tensile test show that the alloy at the state after rolling and consequent heating at 220℃ with holding time of 2 hour has either the highest fracture strength or the highest ratio of the yield strength to fracture strength, meanwhile the plasticity is quite acceptable.
