In this research, Mg9Li2Al1Zn (LAZ-F) magnesium alloy was studied on a friction stir process (LAZ-FSP), and the FSP specimens had stabilized heat treatment (LAZ-FSP-S) to improve the punch-shear properties. LAZ-FSP revealed the network-like structure and particle in the stir zone. Cracks could be found on the subsurface of punch-shear LAZ-F and LAZ-FSP specimens. Notably, specimens with stabilizing heat treatment had no obvious defects on the subsurface after the punch-shear test. It is convincible that stabilizing heat treatment had improved the punch-shear properties of LAZ921. On the other hand, LAZ-FSP shows excellent tensile strength, while LAZ-FSP-S shows a better elongation. Therefore, stabilizing heat treatment at 60°C not only had showed improvements on workability, but also had effectively increased the ductility of magnesium alloy under room temperature.

“…Similar microstructure can be found in previous studies about the Mg-Li alloys casted by ingot metallurgy method. 4,12) The total diffusing thickness (including the mixture layer) was $50 mm for 3.4 V/1 h. A higher applied voltage caused it up to $300 mm for 3.6 V/1 h and $600 mm for 3.8 V/1 h, respectively. The X-Ray diffraction spectra for the electrolytic diffusing samples 3.4, 3.6 and 3.8 V/1 h were indicated in Fig.…”

“…Addition of over 10.3 mass% lithium into magnesium will convert the hexagonal closed pack (HCP) structure to body centered cubic (BCC) lattice, improving formability of the alloy, and reduce its density. [2][3][4] Besides, binary Mg-Li alloy and ternary Mg-Li-Al alloy can be the anodic materials in primary battery systems. 5) According to Sahoo and Atkinson, 5) the Mg-Li-Al alloy can consistently give higher voltages and perform better discharge characteristics.…”

Electrolytic diffusing method was conducted at 500 C to prepare Mg-Li-Al-Zn master alloy in air. It was also explored for the melting and casting of Mg-Li alloy in air, as the Mg-Li-Al-Zn master alloy used as raw material. A mixture of 45 mass% lithium chloride (LiCl) and 55 mass% potassium chloride (KCl) was employed as the electrolyte. Mg-9 mass%Al-1 mass% Zn (AZ91) alloy was used as cathode material while graphite selected as anode. Experimental results showed that the electrolysis current linearly depended on the applied working voltage. Deposition of lithium occurred on the cathode surface. After the electrolysis experiments, Mg-12 mass% Li-9 mass% Al-1 mass% Zn alloy sheet can be obtained. At working voltage of 4.2 V and one hour electrolysis, the hexagonal-closed-pack AZ91D sheet (1.5-mm thickness) was fully converted to body-centered-cubic Mg-Li-Al-Zn alloy. The formation of Mg-Li phase during electrolysis was studied by inductively coupled plasma-atomic emission spectrometer (ICP), X-ray diffraction, and optical microscopy. It is diffusion rather than deposition rate (electrolysis current) that controlled the depth of Mg-Li phase formed in the cathode sample. The Mg-Li-Al-Zn alloy used as master alloys could be melted and casted in air without ignition. However, the content of lithium in the as-cast block was reduced to 3.77 mass%, properly due to oxidation of lithium metal during melting.

“…Efforts of traditional methods are still prevailing to improve strengths by the addition of alloying elements [26][27][28] and mechanical processing, [20,[29][30][31][32][33][34][35][36][37] as a result of their efficiency and economy. Previous works indicate that rare earth (RE) elements, especially the Y element, can improve the mechanical properties of Mg-Li alloys, [26][27][28] and even enable duplex Mg-8Li alloys to present super-plasticity.…”

Mg-8.43Li-0.353Ymm (Y-riched mischmetch) alloy was prepared using the metal model casting method and then hot-rolled at 573 K (300°C) to total reduction of 81 pct, and microstructures and mechanical properties were evaluated. Results show that the rolling procedure introduces great dynamic recrystallization, and b-Li grains in the rolled alloy present an ultra-low average size of 2.18 lm. The ultimate tensile strength and yield strength of the rolled alloy are 158-167 MPa and 124-130 MPa, respectively, 42-63 pct higher than that of the as-cast alloy. The elongation of the rolled alloy is improved to 31-40 pct, as about four to five times that of the as-cast alloy, which is ascribed to the great grain refinement of the b-Li phase.
