“…Then the calculated amount of lithium pellets was added using charging port followed by continuous stirring at 300 rpm for 10 min. After that, the preheated (350 °C) graphene was added through charging port and stirred for about 30 min and then bottom poured into a cast iron mould [19,20]. The cylindrical rod ingot is machined using WEDM and cut into the dimension of 25 mm × 25 mm × 5 mm square sections.…”

In this research, the effect of interrupted rolling on electrochemical corrosion behaviour of Mg-8Li-xGr composite is investigated. Graphene reinforced composite was developed by using stir casting route and rolled with different reductions in thickness of 50, 75 and 90%. Investigation on potentiodynamic polarization of rolled composite depicts that increase in reduction percentage increases the corrosion rate of the developed composite. Electrochemical impedance studies reveal that composite reduced at 50 % thickness exhibits higher charge transfer resistance of 80 cm2. Nyquist plot depicts occurrence of inductance loop that reveals occurrence of oxide layer breakage. Addition of graphene up to 0.4 wt. % increase the corrosion resistance and further addition exhibits adverse effect in corrosion behaviour due to the galvanic effects. The occurrence of pitting corrosion is evidenced from corrosion surface morphology.

In this study, the microstructure and corrosion resistance of the as-extruded and as-extruded with subsequent heat treatment Mg-3Al-1Zn-15Li (LAZ1531) alloys have been investigated. The alloysÕ microstructures consisted of a(Mg), b(Li), H-MgLi 2 Al and Mg 17 Al 12. As a result of annealing, the b(Li) to a(Mg) transformation occurred, and the recrystallization supported the reformation of the Mg 17 Al 12. The electrochemical tests showed that the increased amount of a(Mg) and higher amount of Mg 17 Al 12 in the heattreated alloy favored reactions and determined it as having better corrosion resistance in 3.5 wt.% NaCl.

The microstructure and mechanical properties of hot-rolled Mg-8 wt.% Li and Mg-8 wt.% Li-6 wt.% Zn-1.2 wt.% Y alloys were investigated, and it was demonstrated that due to the formation of the I-phase (Mg 3 Zn 6 Y, icosahedral structure), the crystallographic texture and strength of the alloys is weakened and increased, respectively. At different hot-rolled ratios, the anisotropy (plasticity) of Mg-8 wt.% Li alloy exhibits obviously stronger than the Mg-8 wt.% Li-6 wt.% Zn-1.2 wt.% Y alloy. Failure analysis indicated that ductile fracture occurs along the rolling direction (RD), while quasi-cleavage fracture occurs along the transverse direction (TD). Cracks in the Mg-8 wt.% Li were found to be mainly initiated at the a-Mg phase and the two-phase boundary, which were respectively generated by tensile testing along the RD and TD. The cracks in the Mg-8 wt.% Li-6 wt.% Zn-1.2 wt.% Y alloy were confirmed to be located in the rich Iphase region of the a-Mg phase and at the junction site of the matrix phases.
