contact2021630 · By the 1990s, countries worldwide had strengthened their research on aluminum–lithium alloys, due to the implementation of the low-cost, high-efficiency, long-distance launcher program and the ultra-light fuel tank program [].In particular, the 2195 aluminum alloy has excellent strength, and has been used by the United States to
contact2022415 · A 2219 aluminum alloy plate with size of 90 mm × 60 mm × 12 mm was used as the substrate. Its compositions are listed in Table 1. Pulsed laser melting was performed by a Yb-fiber laser, with a scanning speed of 8 mm s −1 and a shielding gas (argon) of 10 L min −1. The laser power was modulated with a square wave.
contact20211123 · 2XXX series aluminium alloys are widely used in propellant tanks of space launch vehicles. In this work, friction stir welding (FSW) was performed to produce dissimilar joints between 2195 and 2219 alloys. The effect of temperature (ambient, 77K and 20K) on the tensile properties of 2195–2219 joints was investigated. Results showed that
