Precipitation of the ω phase in 2024 and 2124 aluminium alloys

It is shown that Omega phase can form in 2000 series commercial 2024 and 2124 alloys which were solution treated and directly quenched to various aging temperatures (200, 250, 300 deg C) or air cooled to room temperature. The Omega phase nucleated heterogeneously on Mn contaiing dispersoids. Differe...
