The microstructure uniformities and mechanical properties of the 2219 Al–Cu alloy ring should be further improved. Bywhole-process analysis and partial quantitative analysis, this paper studies the microstructure evolution and its influence onthe mechanical properties of the 2219 Al–Cu alloy rings undergoing rolling deformation with different deformation temperatures. The results indicate that, when the rolling temperatures are from hot condition to warm condition, the increase ofthe sub-grain amount leads to more grain refinement after heat treatment; the elongation values clearly increase. The singleGoss texture with high volume fraction is changed to be more varieties after heat treatment, having no significant effecton transverse and normal strengths for each sample. The Al2Cuphases became more dispersed and fragmented, leading tomore dissolve, which results in denser precipitates; the yield strengths gradually increase. In addition, the comprehensiveproperties of the sample on the border are slightly stronger than those on the core, especially for the warm rolling samples.
