| 英文摘要 | In this study, composites reinforced by amorphous Al2O3 (am-Al2O3) and Al11La3 particles, formed through Al-La2O3 in-situ reaction, were fabricated by high energy ball milling (HEBM) and hot-pressing. The difference in high-temperature strength of composites hot-pressed at different temperatures could be as high as 44%, and the reason was disclosed by careful microstructure characterization. It was found that the in-situ reaction could be divided into three processes, accompanied by the crystallization of am-Al2O3 and coarsening of Al11La3. Am-Al2O3 could not only directly strengthen the composites, but also inhibit the coarsening of Al11La3 by forming a film on its surface. Therefore, when the hot-pressing temperature reached the crystallization temperature of amAl(2)O(3) (590 degrees C), am-Al2O3 film transformed into discontinuous gamma-Al2O3 particles, resulting in rapid coarsening of Al11La3 as well as the degeneration of strengthening efficiency. By maintaining Al2O3 in an amorphous state and Al11La3 in fine size, the highest tensile strength of the composites could reach 190 MPa at 350 degrees C. |
