Реферат: The article shows the results of research on microstructural and phase transformation in aluminium-lithium alloys caused by laser welding followed by heat processing based on quenching and artificial aging. The microstructure and phase composition were examined with the help of synchrotron X-ray di raction analysis and high-resolution electron microscopy. Two heat hardenable aluminium-lithium alloys used in the study are V-1461 and V-1469. The chosen alloys are notable for their high corrosion resistance, fracture and fatigue strength. V-1461 and V-1469 are third-generation alloys developed in FSUE "VIAM" and covered by Russian Federation Patents. The research shows that the structural-phase composition of alloys changes in the result of laser welding.
