δ′ Phase Precipitation at Low-angle Grain Boundary in Al-Li-Zn-Zr Alloy

A large number of δ particles precipitated atlow-angle grain boundaries have been observed byTEM in a dilute A1-Li-Zn-Zr alloy during ageingat the suitable temperatures.An explanation forthis phenomenon was proposed,which involves therole of excess vacancies and capillarity effects.
