摘要：

The microstructure and mechanical properties of the ZrB2/7085Al composites containing Sc were studied. The ZrB2/7085Al composites were prepared by in situ reaction via Al-Zr-B system. On addition of Sc, it interacted with Zr present in the alloy resulting in the production of Al-3(Sc, Zr) precipitates. Minor addition of Sc resulted in grain refinement, change in ZrB2 nanoparticles distribution, change in the size and morphology of the eta phase and formation of Al3Sc and Al-3(Sc, Zr) precipitates, which improved the strength significantly. The ultimate tensile strength (UTS), yield strength (YS) and elongation of 7085Al-ZrB2-Sc increased to 660.2, 603.4 MPa and 10.6%, respectively. These tensile properties improved 20.4%, 19.2% and 73.7%, respectively, over the 7085Al.
