This study explores the effect of solution heat treatment, deformation prior to ageing and ageing temperature on the grain boundary microstructure of Al-Li alloys. Emphasis is placed on 8090 but comparison is made with other alloy systems where appropriate. It is concluded that all three variables affect grain boundary precipitation and that the latter two can be used to refine the grain boundary microstructure.
