| Abstract_FL | The effects of Cr on the microstructure of as-cast Al-Cu-Mg-Ag alloys and the distribution,size and number density of dispersoids after double-stage homogenization were investigated by OM,XRD,SEM-EDS and TEM methods. The effects of Cr on the dynamic recrystallization behavior of Al-Cu-Mg-Ag alloys under different equivalent strain were studied by high-throughput isothermal compression experiments. The results show that spherical Al7(Cr,Mn) dispersoids with average diameter and number density of 67.4 nm and 4.7 μm-2 are precipitated during the homogenization process,in addition to the rod-like T-Al20Cu2Mn3 dispersoids. The opposite equilibrium distribution coefficient of Cr and Mn (KMn<1 vs KCr>1) reduces the area fraction of dispersoid-free zones from 29.5％ to 13.8％,the average length of rod-like T-Al20Cu2Mn3 decreases from 275.4 nm to 147.3 nm,and its number density increases from 3.5 μm-2 to 10.4 μm-2. EBSD and tensile test results indicate that the Al7(Cr,Mn) dispersoids hinder the dislocation movement,reducing the transition from low-angle grain boundaries to high-angle grain boundaries during thermal compression,and inhibiting the dynamic recrystallization. The addition of Cr increases the mechanical properties of Al-Cu-Mg-Ag alloys at different temperatures,and the yield strength contributions of Al7(Cr,Mn) dispersoids to the alloys at 25,250 ℃ and 300 ℃ are 21.9,16.2 MPa and 15.3 MPa,respectively. |
