Abstract A new precipitate phase (X phase) has been studied by means of TEMin 2024--2324 Al alloys in different aging conditions. The X phase is determined tohave a c-centered orthorhombic crysta1 structure with a=0.492nm, b=0.852nm andc=0.701nm. It is found that the X phase forms on the helical dislocation in theinitial stage of aging. At lower aging temperature, the S series precipitate phases do-minate the precipitation; while at higher aging temperature, the X phase dominates theprecipitation.

Key words: Al-Cu-Mg alloy TEM X phase
