摘要
The synergy effect of Si addition and pre-straining prior to artificial aging heat treatment on microstructure and mechanical properties of Al-Cu-Mg alloys with a medium Cu/Mg ratio have been investigated by Vickers hardness, room temperature tensile test combined with X-ray diffraction and transmission electron microscopy characterization. It is indicated that the strength was greatly enhanced via adding Si and introducing prestraining due to the formation finer theta' precipitates. The pre-straining was more effective for Si-free alloys on improving strength compared with Si-containing alloys. The combined mechanism of Si addition and prestraining has been discussed in detail.
