摘要

The phase composition of laser welded joints of heat-hardened aluminum-lithium alloys of the 3rd generation of grades B-1461 and B-1469 is studied after a heat treatment consisting of quenching and artificial aging. The phase composition of the heat-treated laser welded joints is studied using synchrotron radiation and high-resolution transmission electron microscopy. The mechanical properties of the welded joints are determined in static tests at normal, elevated and reduced temperatures.
