“…Mg-Li based alloys can be progressively used in the aerospace and aircraft structures as well as in ultraweight communications systems in the future due to their lightweight and strength [1][2][3]. The density of magnesium is approximately two-thirds of that of aluminium, one-quarter of zinc, and one-fifth of steel [4].…”

Mg-Li based alloys are widely applied in various engineering applications. The strength of these alloys is modified and enhanced by different strengthening mechanisms. The strengthening mechanisms of these alloys and their composites have been extensively studied during the past decades. Important mechanisms applied to strengthening the alloys include precipitation strengthening, solution strengthening, grain and subgrain strengthening, and dislocation density strengthening. Precipitation and solution strengthening mechanisms are strongly dependent on composition of the alloys and thermal treatment processes, whereas grain and subgrain and dislocation density strengthening mechanisms majorly depend on thermomechanical processing. In this paper, recent studies on conventional processes for the strengthening of Mg-Li based alloys are summarized as they are critical during the alloys design and processing. Main strengthening mechanisms are objectively reviewed, focusing on their advantages and drawbacks. These can contribute to enhancing, initiating, and improving future researches for alloys design and suitable processing selection.

“…From the OM images, the hot-rolled microstructure under this temperature is not homogeneous with obvious plastic deformation at the surface of the sheet and the almost undeformed microstructure at the center of the sheet. Under this state, some microcracks will exist inevitablely during the subsequent cold rolling, causing the poor strength and elongation [15].…”

The as-cast Mg-14Li-1Zn alloy was hot rolled at different temperatures with the reduction of 50%, followed by cold rolling with the reduction of 80%. The effects of the hot rolling temperature on the microstructure and mechanical properties of the final specimens were investigated. The results show that the higher rolling temperature brings about a more homogeneous microstructure, which is favorable for the subsequent cold rolling. When the hot rolling temperature is 300°C, the final specimen possesses the highest tensile strength and hardness of 238 MPa and 67.7 HV, respectively. When the hot rolling temperature is 200°C, the final specimen possesses the highest elongation of 24.6%.

Al1070/Mg-3Al-1Zn (AZ31)/Al1070 laminated sheets are prepared by roll bonding method. The microstructure and mechanical properties after rolling and annealing are investigated. The layer of Al 3 Mg 2 forms at the interface after annealing at 250 C, and the thickness increases with the increase of annealing temperature. It weakens the bonding strength of the laminated sheets. In addition, during tensile testing, the delamination happens, except for the specimen annealed at 200 C. With the increase of annealing temperature, the dimension of the delamination part increase gradually. The laminated sheets annealed at 250 C possess the best comprehensive properties.
