METHOD FOR PRODUCING AN AL/TIC NANOCOMPOSITE MATERIAL |
| 摘要 |
The invention relates to a process for preparing an Al/TiC nanocomposite material comprising an aluminum matrix in which particles comprising nano-sized TiC are dispersed. It comprises:
a) preparing a first powder mixture by contacting a graphite powder with a titanium aluminide powder of the formula Al3Ti, both powders having micro- or higher sized particles;b) preparing a second powder mixture by mechanosynthesis of the first powder mixture, the second powder mixture being formed in all or part by particles comprising both titanium aluminide and graphite;c) compressing the second powder mixture to obtain one or more greens;d) reactively sintering the green(s), thereby the Al/TiC nanocomposite material is obtained. |
