An aluminum-17 . 5 weight percent copper alloy was warm rolled
to achieve refinement of the microstructure . This refined
microstructure consisted of finely dispersed intermetallic Al^Cu
particles with an average size of 1.2 microns in an aluminum
matrix. This led to improved room temperature properties as well
as the onset of superplasticity at elevated temperatures.
Ductility and toughness were increased almost six-fold, despite slightly decreased yield strength and maximum
compressive strength. It would appear that warm working
can be used to enhance both room temperature properties
and superplasticity, and that further research could
maximize this improvement.
