Microstructures And Mechanical Properties

The influence of aging process on microstructures and mechanical properties of a rapid solidification Aluminum-Lithium alloy has been analyzed in this paper. The results show that the better aging process is as follows: heating to 170oC for 4 hours and then followed by a final aging at about 190 oC for 18 hours. A lot of fine participated second phase such as δ′ in matrix and a narrow participation free band make alloy’s good performance.

Three-phase secondary rectification spot welding machine had been adopted to join 5A90 Aluminum-lithium alloy with a thickness of 2 mm, at different welding conditions. The mechanical properties of the lap joints were investigated and microstructure were analyzed respectively. The results showed that the joint fabricated at a welding current of 45.5 kA, welding time of 4 cycles, and electrode pressure of 8.55 kN exhibited higher tensile-shear force value of 7.7 kN compared to the other joints. The nugget were mainly composed of equiaxial grains and cellular dendrites. Meanwhile, equiaxed zone can be divided into the equated dendrites, the wormlike eutectic structure and few equiaxed non-dendrites. The tensile fracture surfaces exhibited a hybrid ductile-brittle fracture, while Al3Li strengthening phase lied in the bottom of dimple.
